MENDOCINO COUNTY, Calif. – A Lake County man was arrested by a Mendocino County Sheriff’s deputy on Wednesday after he allegedly was found in possession of a number of prescription drugs for which he allegedly did not have prescriptions.

Michael Dean Calas, 28, of Clearlake, was arrested following a traffic stop, according to a report from Lt. Greg Van Patten of the Mendocino County Sheriff’s Office.

At about 10:30 p.m. Wednesday a deputy observed Calas allegedly engaging in an exhibition of speed violation while driving near the intersection of North State Street and Empire Drive in Ukiah, Van Patten said.

The deputy pulled Calas over in the 900 block of North State Street and obtained permission to search the vehicle, according to Van Patten.

Van Patten said the deputy found a backpack which contained numerous prescription pharmaceuticals.  The deputy discovered some of the pharmaceuticals were controlled substances.

Calas allegedly did not have a prescription for any of the pharmaceuticals and was subsequently arrested for the listed violations, Van Patten said.

Calas was transported and incarcerated at the Mendocino County Jail where he was to be held in lieu of $10,000 bail, according to Van Patten.
