NEW YORK (AP) — Authorities say a New York police officer has been shot and is in extremely critical condition.

The New York Police Department wrote on Twitter that the officer was shot while in a patrol vehicle with her partner in the Bronx early Wednesday.

While her partner radioed for assistance, other officers confronted the suspect, who was running, one block away. The suspect drew a revolver and the officers fatally shot him.

Police say another person, believed to be a bystander, was also struck by a bullet. The person is in stable condition.

The 12-year veteran officer has been hospitalized at St. Barnabas Hospital in critical condition.

Authorities say the investigation is ongoing.
