A 16-year-old girl was shot in the head on the Lower East Side on Thursday afternoon, the NYPD said.

Incredibly, the teen is expected to survive and is being treated at a nearby hospital.

Police say the teen was shot inside a building at 210 Stanton St., just south of East Houston by Ridge Street, but it's unclear if it was a targeted shooting or if the victim was an innocent bystander.

Police say the gunman is still on the loose and was last seen wearing a gray tank top and fleeing eastbound on Stanton.
