A man was killed in Brooklyn last night after the limousine he just exited began rolling backward and pinned him against another vehicle, cops said.

Viktor Avaveyev, 53, and two relatives were being escorted out of the limo at around 6:50 p.m. at Kings Highway and Bedford Avenue in Midwood when the tragedy occurred, cops said.

The driver allegedly had put the car in reverse instead of park by mistake.

“I heard an impact and a woman screaming,” said a witness, Yevgeniy Zilberman.

“When I looked out, she was smacking the limo driver and yelling at him. The man was lying on the floor. He must have backed right over him,” Zilberman, 27, said.

The driver, whose name was withheld, was taken into custody, cops said.

Charges were pending early today.
