Car hit at Slope store

A PARKED car rolled onto the sidewalk outside a Brooklyn food cooperative, pinning a man against a gate and injuring his leg, according to authorities and a witness.

The car, a blue compact parked outside the Park Slope Food Coop on Union St. by Sixth Ave., hit the man at 7:40 p.m., authorities said.

Kathleen Keske, who works at the members-only market, says the car may have slipped out of gear and into reverse.

“It just started rolling backward, and it was on an angle on the sidewalk,” she said. “It started slowly backing up on the sidewalk. People were yelling ‘Stop, stop!’ But there was no driver.”

Witnesses sought aid from FDNY Squad Co. 1’s firehouse next door, she said.

The victim, a member of the Food Coop in his 60s, lives in Manhattan and said he was visiting the area with a friend to celebrate his birthday.

“He was conscious,” Keske said. “He was kind of joking about it, ‘What a way to spend my birthday.’ ”

The man, whose identity has not been released, was taken to Methodist Hospital, an FDNY spokesman said.
