Officers raided an address on the White City estate in west London

About 350 officers searched 10 addresses across the city - including a flat on the White City estate in Shepherd's Bush, west London.

The operation began at 0500 GMT and those arrested are suspected of being involved in supplying class A drugs.

Police are hoping to seize suspects' assets and cash if they cannot prove it was earned legitimately.

It is part of a police operation to disrupt London's drugs network using powers under the Proceeds of Crime Act 2002.

Last year the Metropolitan Police confiscated nearly £7.3m in cash seizures and Scotland Yard says it is seizing almost £20,000 a day from criminals.

Assistant Commissioner Tarique Ghaffur said the operation was aimed at hitting dealers "where it hurts the most - in their pockets".

The force starts a two-week advertising campaign about its powers to confiscate assets on Monday.

Another man has been arrested on suspicion of indecent assault.
