Four men have been arrested during an operation targeting an organised crime group.

The operation was led by Hertfordshire Constabulary's specialist county lines team, Operation Mantis, and supported by units from Cambridgeshire Constabulary, the Eastern Region Special Operations Unit (ERSOU) and the Metropolitan Police.

A series of warrants were conducted on Thursday 8 August in Cambridgeshire and Essex, during which three men were arrested. 

Later in the day a vehicle believed to be linked to organised crime was detected by an ANPR camera. 

The vehicle was tracked from Cambridgeshire through Essex and followed by a police helicopter into the London area where it was stopped and a fourth man was arrested. 

Class A drugs, large amounts of cash and other paraphernalia consistent with drug dealing were seized during the operation .

Fatlum Dautaj, aged 24, of Ermine Street North, Cambridge, and Ervis Kastrati, aged 30, of Sackville Close, Cambridge, were charged with conspiracy to supply Class A drugs. Both men have been remanded into custody. 

A 26-year-old man and a 31-year-old man, both from Saffron Walden were also arrested on suspicion of conspiracy to supply Class A drugs and were bailed whilst the investigation continues.

Detective Sergeant Chris Cowell, from Hertfordshire Constabulary's Serious and Organised Crime Command, said: "This operation targeted the 'Ben' line, which was operating in the North and East Herts areas, as well as in South Cambridgeshire.

"We will continue to take a very proactive approach to targeting drug dealing in the county, working with our partners in other agencies to make it difficult for these crime groups to operate, preventing new gangs becoming established and targeting them early before they get a foothold and serious offences can occur."
