SAN JOSE (CBS SF) — A San Jose man was arrested on drug and vehicle theft charges Saturday after a pursuit in Marin County when his pants fell down as he tried to flee, California Highway Patrol officials said Wednesday.

CHP officers were patrolling on northbound U.S. Highway 101 near the Central San Rafael exit around 1:40 a.m. on Saturday when they saw a white Ford F-250 pickup truck swerving in and out of its lanes ahead of them, the CHP said.

The officers attempted to stop the vehicle as it exited at Lucas Valley Road, but the driver accelerated through an intersection and fled east on to Lucas Valley Road, according to the CHP.

The officers pursued the vehicle on to Mt. Lassen Drive, but turned off their lights and sirens after determining that the pursuit was too risky.

A short time later, however, they saw the suspect turn on to Mt. Sustina Court, which had no exit, and were able to block his vehicle in.

The truck’s driver and passenger fled on foot. The passenger was quickly detained by a Marin County Sheriff’s deputy.

The driver continued to flee on foot, and was seen throwing objects into nearby yards, according to the CHP.
