Several drug-related search warrants were served in Danville and four other East Bay communities as part of a multi-agency operation Wednesday, a Dublin police services lieutenant said.
The warrants were linked to three people who ran illegal marijuana grow operations at warehouses in Dublin, San Leandro and Oakland, Dublin police Lt. Herb Walters said.
Additional warrants were served at homes in Danville, Dublin and Castro Valley, as well as at one business in Dublin, Walters said.
The warrants were a result of a six-week investigation originating in Dublin. Pleasanton police, the Alameda County Sheriff's Office and the Alameda County narcotics task force assisted in the execution of the warrants.
