Three people have been arrested in a joint Financial Conduct Authority and National Crime Agency operation targeting a suspected organised criminal group believed to be involved in insider dealing and money laundering. The arrests took place on 13 October, as investigators searched five residential premises in London and Manchester.
More than 100 FCA and NCA staff took part. Investigators seized more than 30 mobile phones, laptops and tablets. The FCA said all three suspects were being interviewed at police stations in the two cities. The operation is an active investigation, not a finding that any individual committed an offence.
What the operation involved
The scale of the searches gives a picture of the resources committed to the inquiry, but does not by itself establish the suspected conduct or the evidence against any person. The authorities have not named those arrested. They have not set out alleged trades, companies, dates, profits or any alleged route for laundering money. The FCA said it could not comment further at this stage and would provide more details when appropriate.
That restraint matters in a case centred on suspected market abuse. Insider dealing generally concerns trading while in possession of inside information, or improperly disclosing such information; the precise statutory offence and facts would need to be established through investigation and, if charges followed, legal proceedings. The present public account does not specify which conduct is attributed to which suspect. Arrest and interview are procedural steps, not proof of guilt.
The FCA and NCA worked together on the searches. The regulator’s enforcement and market-oversight function is responsible for pursuing conduct that threatens the integrity of financial markets, while the NCA tackles serious and organised crime. The joint operation therefore brings together market-abuse enforcement and a broader financial-crime investigation. No inference should be drawn that every person arrested is suspected of every element of the group-level description.
Enforcement in context
The FCA’s own recent figures underline why this action is being framed as a market-integrity matter. In the 2025/26 financial year, it secured four insider-dealing convictions. Two of those cases resulted in prison sentences totalling 11 years. Separately, 12 people were fined a combined £1.77 million for insider dealing, market manipulation and making misleading statements. Those totals span multiple cases and offences; they are not outcomes in the current investigation.
Insider dealing can damage confidence beyond the immediate buyers and sellers in a particular transaction. Investors depend on markets where prices can reflect information fairly and where people with access to confidential, price-sensitive information do not gain an improper advantage. A credible response to suspected abuse can help protect that confidence, but the enforcement process must also distinguish suspicion from evidence and allegation from a court’s conclusion.
The arrest figures and seizures show the breadth of the operation, while leaving its eventual legal direction unresolved. Investigators may continue gathering and examining material from the devices and premises. The public statement does not say what those searches yielded beyond the devices seized, whether any charges are being considered, or when the investigation may reach a decision. These points remain open rather than outcomes that can be inferred from the scale of the operation.
What happens next
For now, the confirmed position is limited but significant: three arrests, five residential searches across London and Manchester, and the seizure of more than 30 electronic devices in an FCA–NCA operation. The suspects were being interviewed, and the authorities had not announced charges or findings. Any later account should be judged against that starting point and should distinguish new evidence or formal decisions from the fact of arrest itself.
The regulator has said that tackling financial crime is a priority in its five-year strategy. Whether this inquiry produces charges, convictions or no further action will depend on evidence and subsequent decisions, none of which has been announced. Until then, the operation is an important enforcement development, but the suspected group’s alleged activity remains unproven.
