CHESTERFIELD, Mo. (AP) – Police in the St. Louis suburb of Chesterfield are searching for a man who broke into a home, robbed a couple and locked them in a closet.

The St. Louis Post-Dispatch reports that the crime happened Thursday night. The man and woman were not injured.

Police say the intruder hid his face with a ski mask. He threatened the couple with a screwdriver, forced them into a closet and locked it. He used the screwdriver to pry open a small safe and got away with undisclosed items.

Chesterfield Police Capt. Steve Lewis says the intruder probably though the home was unoccupied and was surprised by the couple. He says crime is rare in the neighborhood.
