Border Force officers have foiled three separate smuggling attempts at Dover and the Channel Tunnel within the space of three days.
Their first success was in Dover on Friday when 49 gas cannisters were discovered in a Czech-registered van.
The second seizure was also made at Dover the following day when officers found approximately 120kg of amphetamine and eight kilogrammes of cocaine hidden in a lorry.
The drugs have an estimated street value of £400,000.
Both the driver of the van, a 32 year-old man from the Czech Republic, and the lorry driver – a 55 year-old man from The Netherlands, have been bailed pending further enquiries.
On Sunday, officers based at the Channel Tunnel in Coquelles in France stopped and questioned the driver of an Irish-registered Nissan.
After questioning the driver they searched the car and found nine kilos of cannabis hidden in the vehicle.
The driver, a 31 year-old man from Poland, was charged with the attempted importation and appeared at Folkestone Magistrates yesterday (Monday 23 April) where he pleaded not guilty. He was remanded in custody.
Investigations into all three cases are ongoing.
Carole Upshall, of the UK Border Force said: “Border Force officers are on constant alert to keep illegal drugs and other banned substances out of the UK.”
