A vice principal at Elsie Allen High School was arrested on suspicion of drunken driving and carrying marijuana after a state alcohol agent stopped a car speeding on Highway 101, authorities said Wednesday.

Martin Cassity, 42, of Santa Rosa, was released from the Sonoma County Jail on Tuesday after posting bail.

Cassity was arrested at about 10:30 p.m. Monday after a state Alcohol and Beverage Control agent reported a car heading north on the highway had passed him at about 90 mph, then accelerated to about 110 mph, the CHP said.

The ABC agent, whose unmarked car has a red light, pursued the car and attempted to stop the driver. The driver took the Todd Road exit, still speeding, locked up his tires and nearly crashed, the CHP said.

The ABC agent stopped Cassity and alerted the Highway Patrol. Cassity told the CHP he was an employee of Santa Rosa City Schools. He was arrested on suspicion of drunken driving and possessing less than an ounce of marijuana.

Cassity is one of two vice principals at Elsie Allen High School, where he is in charge of discipline of students and campus supervision, according to the school's website. He also is principal of Midrose Small Necessary High School.

Cassity couldn't be reached by phone or email late Wednesday. Officials at Elsie Allen and Santa Rosa City Schools said they weren't aware of the arrest and declined to comment.
