STARKVILLE, Miss. (AP) — City officials have suspended a police chief in a Mississippi college town without explaining why.

Starkville aldermen voted in closed session Monday to suspend Police Chief Frank Nichols for two weeks without pay, followed by six months of probation.

Aldermen named Starkville police Capt. Troy Outlaw as interim chief during the period.

Local news outlets report neither Mayor Lynn Spruill nor Nichols is commenting on the reasons for the action.

Spruill says the probationary period is a means for the city to monitor an employee's job performance.

A breakdown of how aldermen voted won't be released until minutes from the meeting are approved.

Nichols was named Starkville's chief in February 2014. He's worked as an officer in the department since 1992.
