The top job at Pima Community College's Police Department will be filled by the department's second-in-command until a new chief is chosen, the school said Friday.

Commander Manuel Amado, a former Pima County Sheriff's Department deputy, was named PCC's acting police chief after former chief Stella Bay retired suddenly this week.

Bay's decision to leave with a year left on her $100,000 contract came as the college was investigating allegations that her management style created a "hostile work environment" within the campus Police Department.

Amado joined the college in 1996 and has been the department's commander since 2004. He also served as acting chief for three months in 2007.

He serves as a lead instructor in ethics and integrity in law enforcement for the Arizona Peace Officer Standards and Training Board and is a member of a PCC committee that reviews cases of problem behavior on campus.

Amado holds a master's degree in education/human relations from Northern Arizona University.
