A 32-year-old woman was struck in the face by a bullet that flew through the window of her Brooklyn apartment Friday morning, cops said. 

Law-enforcement sources told The Post that a preliminary investigation suggested the victim may have been targeted after a fight with her boyfriend. 

The woman was inside her third-floor apartment on Belmont Avenue near Shepherd Avenue in East New York when she was shot around 7:15 a.m., authorities said. 

She was taken to Brookdale University Hospital Medical Center with non-life-threatening injuries.

Cops are still looking for possible surveillance footage of the incident, according to sources.
