A traffic stop on Highway 29 near Hidden Valley Lake in Lake County led to the arrest of a Sonoma man on suspicion of drug violations, the Lake County Sheriff's Department said.
Deputies searching the man's vehicle found a pound of crystal methamphetamine in a plastic food container that was inside a laptop case on the floor behind the driver's seat, Lt. Steve Brooks said in a press release.
The Sheriff's Narcotics Task Force said it was the largest single methamphetamine seizure in the county this year.
A patrol deputy in the Middletown area spotted a Mazda RX8 with several vehicle code violations about 3:50 p.m. Thursday on the highway near Hidden Valley Road, Brooks said.
A drug detection dog indicated the odor of a controlled substance from outside the car, and when her handler opened the door the dog immediately jumped into the back seat and focused on the floor, he said.
The driver and sole occupant of the car, Luis Fernando Valdivia-Castellanos, 22, was arrested on suspicion of possessing and transporting a controlled substance for sale.
Deputies also seized $1,041 in cash, Brooks said.
