BROOKLYN

*** A 23-year-old man walking down the street in East New York was shot and wounded for no apparent reason, cops said.

Junior Brown, 23, was standing in front of 860 New Lotts Ave. at 10:38 a.m. when he claimed to have been shot in the hand, said police.

He was taken to Brookdale Hospital in stable condition – and is said to have been uncooperative with cops.

“He said he was shot by the bullet fairy,” cracked one detective.

But relatives of the wounded man told The Post Brown had gotten into an argument with another man before a black Ford SUV pulled up nearby and fired a shot, followed by two more. The victim ran into a nearby store after he’d been shot, according to a shopkeeper.
