Hayward police Chief Diane Stuart has been placed on leave pending the completion of a personnel investigation, Hayward City Manager Kelly McAdoo confirmed late Monday.
McAdoo was unable to discuss any other details.
Department spokesman Sgt. Ryan Cantrell said in a statement later that Stuart has been placed on paid administrative leave, and the details of the issue are confidential. Capt. Mark Koller has been appointed as the acting chief by the city manager, the statement said.
According to Stuart's bio posted on the Hayward city website, she started her law enforcement career with the San Jose Police Department in 1986.
Stuart started as an officer and worked her way up to an assistant chief at SJPD. In August 2011, Stuart was selected as the 13th chief of the Hayward Police Department. She was also the first woman to lead Hayward's police force.
