CANNABIS resin worth £50,000 was seized by police at Heysham port last Friday.
Lancashire Constabulary’s ports unit stopped a vehicle in the early hours of July 27 and carried out a search.
They discovered 76 bars of a brown resinous substance, believed to be 9oz bars of cannabis worth an estimated £50,000 in the car’s boot.
In the last few months, officers from the ports unit, working with police colleagues in the Isle of Man and port staff, have seized drugs worth over £315,000.
A search of a vehicle in February revealed an attempt to take £125,000 worth of drugs across to the Isle of Man. During the TT races £140,000 worth of drugs were also seized.
Detective Superintendent Martin Kay from Lancashire Constabulary, said: “Criminals may try to take drugs in or out of the county via our ports but they should know that they are being watched very closely.
“We take the policing of our ports very seriously and will work with port teams, other agencies and police colleagues on both sides of the water to provide a visible and effective deterrent to cross border crime and to make sure that our busy ports are secure.”
He added: “We would ask residents to help us in this aim by reporting suspicious activity involving boats or aircraft, or around coastal areas.”
Information can be given to police on 101.
