Over the past four months, police say he has struck at least four times. In each case, he has entered, displayed a firearm, tied up employees and made off with cash and other items.
"I'm scared, I believe that maybe he shoot me," said one of the store clerks, Inderjed Singh.
He remembers that gun and the fear he felt when the man robbed the newsstand where Singh was working.
"He tied my hands. He says, 'Where is the money?' The money was on the counter and he take all the money," said Singh.
On Nov. 27th, the robber stole $2,000 cash, over $1,000 worth of Lotto tickets and $500 worth of prepaid cards from a store on Lexington Avenue.
On Dec. 3rd, he took over $1,000 from a grocery store on Broadway on the Upper West Side.
Then on Jan. 30th, police say the man stole over $4,000 from a newstand on the West Side.
And on Feb. 15th, he made off with about $2,000 and cigarettes from an East Side smoke shop on First Avenue.
('Did he have a gun?') "Yes," said store clerk Md Karam Hossain. ('Did he point it at you, wave it at you?') "I saw it in his hand. His hand and gun," said Hossain.
Hossain was working at the first store. He was suddenly surprised by the armed robber as he was pulling the newsstands from in front of the store.
"I never had that before, that's why I was scared," he said.
The suspect demanded money and grabbed prepaid phone cards. I showed MD the pictures of the suspect but he didn't see much of the man's face.
The suspect is described as a male, white, 40-50 years of age, approximately 5'8" in height, with a medium build. He was wearing a black Chicago White Sox baseball hat with the word CHICAGO printed across the front.
