Manchester (Manchester Mirror) October 14, 2026 – Three people have been arrested in a major joint operation by the Financial Conduct Authority and the National Crime Agency targeting a suspected organised criminal group involved in insider dealing and money laundering.

The FCA said the arrests were made on 13 October after more than 100 FCA and NCA staff carried out searches at five residential premises in London and Manchester. The regulator said investigators seized more than 30 mobile phones, laptops and tablets during the operation.

As reported by Reuters, the three individuals were arrested on suspicion of being involved in a criminal insider dealing and money laundering plot. The news agency said the FCA announced the action on Tuesday, 13 October, and that the suspects had not been named.

The FCA said all three suspects were in the process of being interviewed by its investigators at police stations in London and Manchester. It added that it could not comment further at this time and would provide more details when appropriate.

What did the FCA say about the operation?

The FCA described the action as a major operation to disrupt a suspected organised criminal group engaged in insider dealing and money laundering. It said the arrests followed a joint operation with the NCA.

In its statement, the regulator said that more than 100 FCA and NCA staff participated in searches at the five residential addresses. It did not identify the locations beyond saying that they were in London and Manchester.

The FCA also confirmed that more than 30 mobile phones, laptops and tablets were seized. It did not say what material investigators believe the devices may contain, nor did it disclose the identities, ages or occupations of those arrested.

As reported by MLex, the FCA said interviews with those arrested were taking place. MLex described the action as part of a “major operation” against suspected insider trading.

Why were the three people arrested?

The FCA said the suspected conduct involved insider dealing and money laundering. Insider dealing refers to trading, or encouraging others to trade, using confidential, price-sensitive information that has not been made public. Money laundering involves concealing the origins of criminally obtained money or property.

The regulator did not say which companies, shares, transactions or time period were under investigation. It also did not say whether any further arrests, charges or regulatory actions were expected.

Reuters reported that the FCA said it could not comment further at this stage. The agency’s report also noted that the regulator had recently increased enforcement action in suspected insider dealing cases, including matters involving an oil rig consultant, traders and a financial adviser.

The FCA’s statement did not allege that the three arrested individuals had been convicted of any offence. An arrest is not a finding of guilt, and any criminal case would depend on evidence assessed through the appropriate legal process.

What did Steve Smart say?

Steve Smart, the FCA’s executive director of enforcement and market oversight, said insider dealing posed a serious threat to the integrity of UK markets.

As quoted in the FCA’s press release, Mr Smart said:

“Insider dealing is a serious threat to the integrity of our markets. Working with partners, we will continue to use all the powers at our disposal to crack down on serious and organised crime groups engaged in market abuse.”

Reuters also carried the same statement, attributing it to Mr Smart in his role as the FCA’s joint enforcement head.

The FCA did not provide a comment from the NCA in its press release. It also did not say whether the NCA had made a separate statement about the operation.

How large was the FCA and NCA operation?

The operation involved more than 100 staff and officers from the two agencies. The FCA said they searched five residential premises in London and Manchester.

Bloomberg reported that the three unidentified individuals were arrested on Tuesday and that officers from the FCA and NCA searched five homes in the two cities. Bloomberg also reported that more than 30 mobile phones, laptops and tablets were seized, citing an emailed statement from the regulator.

The scale of the deployment suggests a coordinated enforcement action rather than a single-address search. However, the FCA has not disclosed how long the operation lasted, whether it was connected to a specific market event, or whether investigators are examining activity involving UK-listed companies.

What happens next in the investigation?

The FCA said the three suspects were being interviewed at police stations in London and Manchester. It said it could not comment further at the time of its announcement.

No charging decision has been announced. The FCA may decide, following its investigation, whether to bring criminal proceedings, take civil or regulatory action, or close the matter without further public action. The regulator did not set out a timetable for any next steps.

The FCA said people with information about insider dealing could contact it by telephone on 0800 111 6768 or through its reporting form. It said information could be passed confidentially.

How does this fit into FCA enforcement?

The operation comes as the FCA continues to prioritise financial crime under its five-year strategy. The regulator said fighting financial crime is one of its priorities.

In 2025/26, the FCA secured four insider dealing convictions. It said two of those cases resulted in record sentences totalling 11 years of imprisonment.

The FCA also said 12 people were fined a total of £1.77m during that period for insider dealing, market manipulation and making misleading statements.

Reuters reported that the regulator has stepped up enforcement in suspected insider dealing matters. Its report cited recent cases involving an oil rig consultant, traders and a financial adviser, although it did not link those cases to the latest arrests.

The Times reported that Nikhil Rathi, the chief executive of the FCA, said the investigation came amid a rise in financial crime that was becoming increasingly sophisticated.

Background of the development

The FCA is the UK’s conduct regulator for financial services firms and financial markets. It has powers to investigate market abuse, including insider dealing, and can work with law enforcement bodies such as the NCA where suspected criminal conduct is involved.

Insider dealing is treated as a serious market abuse offence because it can undermine confidence in fair and transparent markets. It involves using non-public, price-sensitive information to gain an advantage in trading, rather than relying on information available to the wider market.

The latest action follows a period in which the FCA has publicised a series of insider dealing convictions and fines. In 2025/26, it secured four insider dealing convictions and imposed £1.77m in fines on 12 people for insider dealing, market manipulation and misleading statements.

The FCA’s joint action with the NCA also reflects its stated approach of using partnerships to address serious and organised financial crime. Mr Smart said the regulator would continue to use all available powers against organised crime groups engaged in market abuse.

Prediction: What it means for UK investors

For UK retail investors, the development is likely to reinforce the importance of trading only on publicly available information and being cautious about unofficial “tips” or confidential market information. The FCA has said insider dealing threatens market integrity, and its latest operation indicates continued enforcement attention on suspected organised market abuse.

For financial services firms, compliance teams may face greater pressure to monitor employee trading, information barriers, communications and suspicious transaction patterns. The seizure of more than 30 devices suggests that investigators may examine communications and digital records as part of the inquiry, although the FCA has not said what evidence it is seeking.

For markets more broadly, the arrests are unlikely to have an immediate, identifiable market impact because the FCA has not named the individuals, companies or securities involved. However, continued high-profile enforcement can support confidence that UK regulators are prepared to investigate suspected abuse, particularly where it is alleged to involve organised groups.

The most significant outcome for investors will depend on whether the FCA brings charges, secures convictions or discloses further details about the alleged scheme. Until then, the public record remains limited to the arrests, searches, device seizures and the regulator’s statement that its investigation is ongoing.
