LONDON, (Reuters) – Police arrested eight people yesterday suspected of sending drugs money to Jamaica in an  international money laundering network, Scotland Yard said.

More than 100 officers arrested four men and three women in  raids on five addresses in London, and picked up a further man  in Cambridge.

Police said the operation followed a lengthy investigation  led by the Metropolitan Police’s Operation Trident, which  tackles gun crime in London’s black community.

It said they had been working closely with police in Jamaica  and Miami.

Detectives began their probe after discovering a criminal  network sending regular sums of cash from drug dealing in south  London to associates in Jamaica.

They believe the proceeds were invested in substantial  properties in Miami.
