NEW YORK (CBSNewYork) — Police are searching for a man they say pistol whipped a vendor and robbed his Manhattan newsstand.

The attack happened on a very busy stretch of Fulton Street, just a couple blocks from the 9/11 memorial.

Mobarok Karim, a Bangladeshi immigrant, was working alone just before 8 p.m. two weeks ago when he was ambushed by a man with a gun, CBS2’s Brian Conybeare reported.

Surveillance video shows Karim getting ready to restock the sodas outside. When he opens a locked door, the suspect hits him in the head with a silver pistol. The man then forces Karim down, covers his head and even throws a case of bottled water on top of him. He then grabs more than $3,000 from the cash register, stuffing it into his pockets and down his pants.

Police said he also stole rolls of scratch-off lottery tickets.

Karim was hospitalized for a head injury, but is now back to work, despite the terrifying incident.

“I just opened the door to fix something here, and he was beat me with a gun,” he told Conybeare in an exclusive interview. “I don’t see him, I just look around this way. And he just beat me right on the head. And when I look at him, he said, ‘whatever you have, just give me. Otherwise, I’ll shoot you.'”
