SACRAMENTO  (AP) — The California Highway Patrol said Friday that it has arrested a state employee who is accused of bringing a loaded gun to work at the secretary of state’s office.

Security officers discovered a backpack with a loaded gun left in a men’s bathroom at the agency’s downtown Sacramento office on Monday, a state holiday, Officer Sean Kennedy said. CHP officers questioned Bryan Thurmond, 50, when he came to work the next day and arrested him on a misdemeanor charge of possessing of a firearm in a state building.

Officials could not say whether Thurmond accidentally left a gun in his bag or planned to use it. The California Highway Patrol would not release the police report until it was reviewed by lawyers.

The secretary of state’s office on Friday afternoon obtained a restraining order against Thurmond, who was released Thursday from the Sacramento County Jail.

“When he came to work on Tuesday, it’s my understanding he went into that same restroom, but the bag was not there,” Chief Deputy Secretary of State Bill Mabie said. “There was reason enough to have concern to seek a restraining order.”

CHP has been providing additional security in the building’s lobby. Secretary of State Alex Padilla has ordered a security review of the building, which does not have metal detectors and does not screen visitors.

Thurmond is a temporary employee who has worked in the agency’s business filings division since July 2013, Mabie said. Thurmond previously worked for the department from 1992 to 1993.

Kennedy did not know what type of gun was discovered or whether Thurmond had a criminal history. He is scheduled to be arraigned on Feb. 11.
