A GANG of suspected Vietnamese drug farmers were questioned by the Border Agency after a series of dawn raids in Liverpool.
Officers arrested 13 suspected illegal immigrants with around £1m worth of cannabis and £14,000 cash was seized during Operation Juliana.
In the joint operation with Merseyside police yesterday more than 150 officers raided nine city addresses searching for people suspected of being smuggled into the country to grow cannabis.
Border Agency officers believe the gang leaders have also been identified and suspects are being questioned in Merseyside police stations.
Dave Magrath, Head of the UK Border Agency crime team in the North West, said: “We have safeguarded communities in Liverpool by uncovering and apprehending those who have no right to be in the country and are involved in criminal activity across our city.”
Six cannabis factories each with several hundred plants were raided across Liverpool.
In Gilroy Street, Kensington, armoured and helmeted officers smashed their way into three properties using battering rams.
