A New York City police officer was killed on Wednesday in the Bronx by a gunman who was then shot and killed by police as he ran from the scene, police said.

The officer, Miosotis Familia, a 12-year veteran of the force, was shot as she sat in a police vehicle with her partner at about 12:30 a.m. local time, the New York Police Department said.

The 48-year-old officer "was shot in an unprovoked attack," the department said.

Officers chased the assailant on foot for a block before he drew a revolver and they shot and killed him, the department said.

A bystander was also shot and was in stable condition, according to the department.
