Two girls were among three bystanders shot in The Bronx last night by gang-bangers chasing a man, police sources said.

Two assailants were pursuing a foe down Astor Avenue in Bronxdale when they opened fire just before 8 p.m. and hit a 49-year-old man in the head as he stood working on a ladder in front of a deli, the sources said.

The hoods then chased their mark into the deli and started blasting again, this time striking a 15-year-old girl in the stomach and a 12-year-old girl in the leg.

The victims were treated at area hospitals for wounds described as non-life-threatening.
