NEW YORK (CBSNewYork) — The search continued late Thursday for suspect who police say punched a subway passenger in the face for no apparent reason.

It happened back on Feb. 6 on board a northbound 7 train.

As CBS2’s Janelle Burrell reported, the reports of the attack alarmed riders at the Main Street terminal in Flushing Thursday.

“I was shocked, of course,” said Lucy Bodden.”Everyone that was on the train heard about it we started.”

Khurram Safri, 36, says he was riding the train on his way home from work. He said he was on the uptown train watching the suspect harassing other passengers when the man randomly attacked him.

“He suddenly came and just punched me and my head is banged into the car,” Safri said.

The impact of the punch, he said, knocked him out.

“For like 10 seconds, I was unconscious and when I wake up my coworker, he hold that guy,” Safri said.

When he train pulled into the Main Street station in Flushing, police said the man walked off the train and out of the station.

Safri was glad no one was seriously hurt.

“God forbid he hit some old man, some lady or some kid,” Safri said. “It could be very dangerous.”

Other commuters agreed.

“People have messed up minds these days,” said Charlie Herrera of Flushing. “Don’t know what else to say — be careful in the streets.”

The victim was left with cuts and bruises to his face, but refused medical attention at the scene.

Police have released surveillance video of the suspect moments after the incident as he walked out of the station.
