A wild shootout between cops and a gunman on a Brooklyn street last night left two people dead — including a mother caught in the crossfire as she sat on her stoop with her daughter.

The bullets began flying at 9 p.m., on Park Place in Crown Heights five hours after the end of the Caribbean Parade, which had passed four blocks away.

The violence was set off when Randy Johnson and Leroy Webster got into a post-parade brawl inside 637 Park Place, officials said.

“There was an argument and somebody came back and started shooting,” said a witness Shareem Braxton.

Another witness said the two young men had been “slap boxing” and the loser threatened to come back with a gun.

“They had a dispute apparently in a hallway and started throwing punches, and one got a gun and started firing,” Mayor Bloomberg told reporters at Brookdale Hospital, where the officers were taken.

The fight spilled into the street, where Webster fatally shot Johnson in the neck, said Police Commissioner Ray Kelly.

Another police source told the Post the two may have also been involved in an earlier drug transaction.

When cops arrived, Webster refused to surrender and opened fire, Kelly said.

“Tragically, one of the criminals fired shots that killed an innocent bystander named Denise Gay,” Bloomberg said of the 56-year-old bystander, who was hit in the head by a stray bullet.

“We saw cops with weapons drawn and a suspect running down the street. The cops were shooting at the suspect and the suspect was shooting also,” another witness said.

Eight officers fired about 70 shots, a source told the Post. The barrage killed the gunman. It’s not clear how many shots he fired.

Officer Avichaim Dicken, 24, suffered a graze wound to his arm and was released after treatment at Brookdale Hospital. Officer Omar Medina, was hit by bullet fragments in his face and leg and was admitted in stable condition.
