Wiltshire Police mounted their biggest single day of action on Wednesday 29 January as part of the long running Opeation Harness.
After months of planning, over 400 staff from Wiltshire Constabulary and partner agencies including Immigration Control were involved in executing warrants at more than 60 addresses in the Swindon area.
The aim was to hit the suppliers and dealers of Class A drug who have been infecting the town and to disrupt supply chains from gangs in London, particularly in the Borough of Greenwich.
Arising from intelligence collected from previous Operation Harness days of action and resulting investigations, members of the Wiltshire police worked with colleagues in the Metropolitan Police in executing warrants at addresses in different parts of London.
The operation was so large that the police had to gather all 400 officers and staff at the former RAF base at Lyneham before a convoy of over 50 vehicles set off through Royal Wootton Bassett to hit the addresses across Swindon.
