Chilling police audio captured the frantic moments after an officer was stabbed in the neck during a confrontation with a man in Brooklyn.

An officer can be heard yelling “Help!” in the tape posted by Broadcastify as the dispatcher repeatedly asks, “What’s the location?”

“Where you at?” he asks but gets no immediate response as a violent struggle is heard in the background.

“What’s the location? What’s the location?” the dispatcher asks with increased urgency.

At one point, someone is heard saying an officer was stabbed.

A female officer then shouts for a “bus,” referring to an ambulance, to be sent.

The dramatic clip emerged as members of the FBI’s Joint Terrorism Task Force arrived at the scene of the stabbing early Thursday.

FBI agents also were seen at the Flatbush apartment building of the 20-year-old suspect, whose name has not yet been released.

The suspect approached an officer and stabbed him in the neck, a police source said. Several cops responded and one pulled his firearm, sources said.

The officer and the suspect struggled for the weapon, which went off, striking one officer in the hand and another in the arm.

A sergeant also responded and shot the suspect, police said. The police officers were rushed to Kings County Hospital with non-life-threatening injuries, authorities said.

The officers were listed in stable condition Thursday morning. The suspect was in critical condition.
