MESA, AZ (AZFamily) — Mesa city officials confirmed on Monday that another top commanding officer is under investigation in the police department.

Commander Diana Clevenger is the focus of an internal investigation. It’s unclear what she’s being investigated for, and the city isn’t providing any additional details.

Clevenger announced her plans to retire on Jan. 3, the city said.

Back in September, Mesa police confirmed that assistant police chief Ed Wessing was being investigated for misconduct and he had been reassigned to his home.

It’s unclear what rules or policy violations are being investigated.

Wessing was in the running to become the next chief of the Phoenix Police Department earlier this year.
