A 29-year-old female pedestrian is in critical condition after a crash involving a Buffalo police vehicle.

Four others including a Buffalo police officer were also hurt. Authorities say their injuries are non-life threatening.

It happened Wednesday at Main Street and Benwood Avenue.

Spectrum News has learned the officer is a three-year veteran of the department.

Authorities say the officer was responding to a knife call.

The Erie County district attorney and state attorney general's office have been contacted, which police leaders say is protocol.
