SIMI VALLEY, Calif. (AP) — Authorities say a Southern California police officer once named his department's officer of the year has been arrested on suspicion of stealing more than $100,000 in public funds by lying on his timesheet about overtime.

Officials in Simi Valley say Officer Robert Longdon turned himself in Tuesday to prosecutors and was subsequently taken into custody. He could face charges including felony grand theft. It wasn't immediately known if he has an attorney.

Prosecutors say the 44-year-old padded his reported hours and falsely claimed to have worked more than 60 10-hour shifts.

Police Chief David Livingstone called the arrest embarrassing.

The Ventura County Star says Longdon was named Simi Valley officer of the year for 2012.

The 10-year department veteran faces more than five years in jail if convicted.
