Wu said that the Financial Conduct Authority (FCA) of the United Kingdom and the London Police Department recently launched a joint operation to arrest two people suspected of operating an illegal crypto asset exchange. The two suspects, aged 38 and 44, are suspected of buying and selling more than 1 billion pounds of unregistered crypto assets through the business. The FCA inspected the offices associated with the suspects, and the police seized multiple digital devices in two residences in London. The two suspects have been questioned by the FCA and released on bail, and the investigation is still ongoing. Therese Chambers, executive director of enforcement and market supervision at the FCA, said that the FCA will do its utmost to prevent illegal crypto businesses from operating in the UK, and emphasized that crypto asset exchanges must be registered with the FCA and comply with the UK's anti-money laundering regulations to operate legally.
