A driver who attempted to smuggle liquid amphetamine worth more than £1 million into the UK through Dover hidden in a windscreen washer bottle has been jailed.

Border Force officers stopped 32-year-old Marcin Leon Prokop, a Polish national living in Leicester, as he arrived at Dover’s Eastern Docks on October 22.

When they searched his British-registered Peugeot tests showed that a yellow liquid in the windscreen washer bottle contained amphetamine.

Prokop told investigators from the National Crime Agency that he collected the drugs in Belgium and was due to deliver them to a location in Birmingham, where he would be paid around £2,000.

The bottle contained eight litres of the liquid, which if processed and sold would have had an estimated street value of £1.19m.

Prokop later admitted a charge of attempting to import a controlled drug and at a hearing at Canterbury Crown Court on Friday he was sentenced to three years and four months in prison.

He faces deportation after serving his sentence. at Canterbury Crown Court on Friday he was sentenced to three years and four months in prison.

Malcolm Bragg, from the NCA’s Border Policing Command, said it was a clever concealment and demonstrated the lengths criminal groups would go to in an effort to avoid detection.
