The Lassen County Sheriff’s Office says 28 people have been arrested after an operation investigating drug and gang activity, and more people are being sought. It’s part of a multi-agency operation led by Lassen County and the Susanville Police Department. More than 200 local, state, and federal law enforcement personnel executed state search warrants in and around the Susanville area, as well as outlying areas of Lassen County. The operation targeted alleged methamphetamine and heroin storage and distribution centers operated by what Lassen County says is called the Susanville White Boys gang.
