TUCSON, Ariz. (AP) — Tucson police say a man who chased robbers after they shot their way into his home was wounded when one of the robbers fired an assault weapon from a car window at the man's pursuing vehicle.

Police say the wounded man pulled over and was treated for injuries considered non-life threatening but that a police helicopter pursued the robbers' vehicle and that two people were detained after the vehicle stopped and its occupants scattered.

Sgt. Pete Dugan says the incident began early Thursday morning when the men shot through a sliding gas door, entered the home and took items before leaving.

Police say drugs and paraphernalia were found in the home and that they didn't consider the home invasion a random act.
