Ballistics tests on a bullet pulled from the vest of one of two officers wounded during a weekend confrontation with a gunman show it came from the suspect's revolver, police said Monday.

New York Police Department Officer Andrew Yurkiw was struck in his bullet-resistant vest during the Saturday morning shooting in Brooklyn that touched off after the suspect slammed his car into a police vehicle. Officer William Reddin was struck in the hip; tests were still being conducted on fragments to try to determine where that shot originated, police said.

City officials said more than 30 rounds were fired during the chaotic scene, and it wasn't clear initially whether the officers had been struck accidentally by police bullets. Several officers converged on the armed driver and fired while he was in his car.

The suspect, Jamal Funes, was hit multiple times and is in critical condition. Police recovered a .357 Magnum in the front seat of his car. Police say he had earlier pointed a gun at officers before fleeing.

The shooting came a little more than two weeks after Officers Diara Cruz and Patrick Espeut were shot and wounded on patrol in a public housing stairwell in the Bronx by a gunman who killed himself soon after, police said. Last month, Officer Sherrod Stuart was wounded in the ankle by a police bullet as another officer exchanged gunfire with a suspect in a Bronx street brawl.

In October, Officer Randolph Holder was shot and killed by a suspected bicycle thief he was chasing in Manhattan.
