Avon and Somerset Police arrest 270 during Relentless
More than 300 people have been arrested in a "day of action" across the Avon and Somerset area, police have said.
Approximately 1,000 officers were involved in a series of dawn raids as part of Operation Relentless.
Cannabis-growing operations were found, including ones in Bath, Highbridge, Felton and Weston-super-Mare.
The force said it was one of its "biggest operations this year". More than 3,500 arrests have been made under the banner since its 2005 launch.
"Relentless has been running for seven years," said Assistant Chief Constable Anthony Bangham.
"[It] has two main aims - reinforcing what we do on a daily basis in targeting criminals head-on and providing further public reassurance through visible, high-impact policing."
The action is part of a campaign to tackle criminals involved in motor crime, burglary and robbery. Over the past two months more than 1,200 suspects have been arrested.
