An Albanian gang supplying cocaine to City workers in the capital's Square Mile has been jailed for 33 years.

The twelve-strong gang, comprising two lieutenants, eight couriers and two others were caught with 1.2 kilos of the drug, worth over £100,000.

City of London Police also recovered £20,000 cash and two phones used by the controllers.

Police conducted an eight month undercover investigation after a courier was stopped on a routine check and cocaine was found.

A series of trials began last year at Inner London Crown Court and the Old Bailey.

Detective Constable Lee Johnson, who led the operation for the City of London Police, said: “A lot of individuals delivering drugs across the capital are young and vulnerable people who are being exploited.

"Many people don’t realise it, but money from selling drugs can be used to fund other serious offences.

“This operation has been incredibly successful in disrupting a large and organised group of criminals, making a profit from the sale and distribution of cocaine in the City.

“The arrest and sentencing of these individuals sends a strong message both to people coming to the City to sell drugs and those in the City buying them: this will not be tolerated by police.

"We are doing all we can to bring those responsible for selling drugs to justice and to protect those at risk of exploitation.”
