The UK Financial Conduct Authority and National Crime Agency have arrested three individuals in a major operation targeting a suspected organized criminal group involved in insider dealing and money laundering. More than 100 staff searched five residential properties in London and Manchester, seizing more than 30 mobile phones, laptops and tablets. The suspects are being interviewed by the FCA at police stations in London and Manchester. The operation follows four insider dealing convictions secured by the FCA in 2025-26, including two record sentences totaling 11 years in prison, while 12 people were fined a combined GBP 1.77 million for insider dealing, market manipulation and making misleading statements.
