Police have arrested 26 people and seized drugs worth £8,000 in a week of raids across the north-east.
Officers also seized £4,300 in cash and four weapons as part of the operation, which targeted known violent offenders.
Detective Chief Inspector Finn McPhail said: “Enforcing warrants, tackling violence and disrupting drug crime is routine business for all our officers across the region every day.
“I hope this operation sends a very clear message that violent crimes will not be tolerated.”
