The U.K Financial Conduct Authority has expanded its enforcement action against crypto ATMs, taking the investigation to east London after working with West Yorkshire Police to tackle crypto ATM operators in the northern city of Leeds.

The financial regulator is working with the Metropolitan Police and inspecting "several sites in East London suspected of hosting illegally operating crypto ATMs," said Wednesday.

All companies providing crypto services in the U.K. must be registered with the FCA for compliance with anti-money laundering and counter-terrorist financing. The regulator has previously said that none of the crypto asset businesses registered with it are authorized to provide ATM services. So any crypto ATMs operating in the country are doing so illegally.
