A former Michigan State Police sergeant was arrested on Monday for allegedly stealing from the Cadillac Post evidence room.

Malcolm Irwin was arrested on charges of embezzlement by a public official and embezzlement of an agent or trustee $1,000 or more but less than $20,000.

Officials say the investigation began in March of 2014 when they were alerted that around $9,600 was missing from the Cadillac Post property room.

Irwin was in charge of the evidence room.
