Macon County authorities say a part-time police officer from Warrensburg has been arrested for allegedly sexually assaulting a 9-year-old girl.
Decatur Police detectives say they arrested 42-year-old Douglas H. Spensley Wednesday morning at his Decatur home without incident.
Deputy Decatur Police Chief Todd Walker said Spensley was believed to be a family friend of the victim's parents.
Spensley was charged with predatory criminal sexual assault and was being held on $500,000 bond.
Spensley, who has been on Warrensburg's police force since 2006, has been placed on unpaid administrative leave, pending an internal investigation and any other criminal proceedings.
