A group of men from across London have been sentenced for importing 1,500 kilos of cannabis into the UK from Ghana in sacks of Gari powder. 

The National Crime Agency (NCA) linked four men to the huge drugs quantity after it was discovered inside a shipping container at Tilbury Docks, Essex. 

Daniel Yeboah, 54, of High Street, Hackney, Kristoffen Baidoo, 48, of Stratford, Kwaku Bonsu, 52, of Arthur Road, Edmonton, and Edward Kwame Adjei of London Road, Grays, were found guilty of importing the class B drug last month.

The finding followed a three-week trial at Southwark Crown Court. 

The drug-filled container arrived to the docks from Ghana on December 19, 2019, and was searched after intelligence suggested it contained narcotics.

The estimated street value of the drugs would have been approximately £4.3 million. 

The drugs were removed from the sacks and replaced with dummy packages. 

The container of prop packages was tracked moving from the docks to an industrial yard in north London on the back of a lorry on January 13, 2020.

Bonsu was seen circling the industrial yard in his car and taking photographs of the shipping container on his phone. 

Adjei was spotted by NCA officers dropping Baidoo off at the yard.

The men were followed by NCA officers and arrested later that day.

At Baidoo's home address a ten-tonne hydraulic press, often used to compress drugs, was found during a search of the property. 

Several devices were seized from the men, including mobile phones and dash cams.

He was heard speaking with Yeboah, saying: "My brother, be a little watchful. It is all a little dodgy."

Yeboah was recorded on later calls telling Adjei: ""I don't think the food [drugs] is in it" and, "there was Gari inside, they have removed most of the Gari. The people are thieves."

Payments made to a shipping company for the delivery of the container to the yard site were linked to a bank account held my Bonsu. 

All four men were sentenced at Southwark Crown Court today (October 18).

Adjei received a four year prison sentence for the same charge. 

Baidoo failed to appear at the trial last month, and Bonsu fled the jurisdiction prior to sentencing.

Work is ongoing to locate the pair and return them to custody to carry out their sentences. 

NCA senior investigating officer Saju Sasikumar said: "These men used their international contacts to import a huge amount of cannabis into the country.

"Its onward supply in the UK would have had a catastrophic impact on our communities, fuelling violence and exploitation through county lines drug dealing."
