Worcester police have arrested two men they say were shooting people with a BB gun. Two victims, reportedly shot in the head Wednesday morning, were taken to a hospital for treatment of injuries not considered life-threatening. Witnesses said a third victim, a woman struck in the leg, left the area before police arrived. Police charged Christian Cruz, 19, and Kennie Mota-Cruz, 20, with three counts of assault and battery with a dangerous weapon and discharge of a BB gun or air rifle on a public way. Authorities said they were shooting from inside an apartment.
