ST. PETERS, Mo. -- Authorities investigating complaints a suspicious bag was left outside a suburban St. Louis dressing room have found images of nude and partially clothed women on a man's phone.

KMOX-AM reported police began investigating after a woman became concerned about an oddly placed bag with a small hole in it while trying on clothes at Mid Rivers Mall in St. Peters. Police officer Melissa Doss said in a statement the woman provided a description of a man.

After the same thing happened in Chesterfield, Missouri, investigators caught a 47-year-old man. Doss said there are 20 or more unidentified women in photos found on the man's phone.

Police want to hear from people who noticed a suspicious bag while shopping at Mid Rivers Mall in late December and early January.
