Four arrested in suspected money laundering raids
Four people have been arrested as part of an investigation into a suspected multi-million pound money laundering network, the UK Border Force has said.
Three men and a woman were detained after officers swooped on properties in London and Surrey.
Documents, mobile phones and computers were also seized in the raids.
The investigation began when officers seized about £300,000 in cash from a passenger at St Pancras International rail station last September.
Senior investigating officer Peter Avery said the "complex financial investigation" had involved close co-operation between the Border Force, various police forces and HM Revenue and Customs.
A 63-year-old was arrested in Weybridge, Surrey, a 38-year-old man in Harrow, north London, and a 45-year-old man in Teddington, south west London.
A 33-year-old woman was held by police at a business address in Hampton Hill in south west London.
They are being questioned on suspicion of money laundering.
Police also carried out searches at business addresses in Hampton Hill and Docklands, south east London.
