A Westbury man wielding a box cutter told an acquaintance that he was going to rob him, then joined two others in chasing down the man and beating him during the robbery, Nassau police said.
Ayman Humud, 23, of First Avenue, was arraigned Wednesday on a charge of first-degree robbery. Bail was set at $50,000 bond or $25,000 cash.
Humud had been arrested Tuesday, one day after the attack, which left the victim with head and back injuries, police said.
Investigators said the acquaintance, 42, got into a Nissan Maxima on Monday morning with Humud, who was driving, and two other men that he did not know. Humud drove to the intersection of Meyer Street and East Greenwich Avenue in Roosevelt, where he took out a box cutter to rob the acquaintance, telling him "this is a robbery, get the [expletive] out of the car," according to the complaint against him.
The acquaintance ran out of the car, but Humud and the two passengers caught up and started kicking and punching the man, police said. One of the men "tore" from the victim a book bag containing medication, two silver chains, money and a cellphone, then took medication and another cellphone out of the victim's pants pocket, the complaint said.
The three suspects took off in the Nissan after the robbery, which occurred about 10:30 a.m., police said.
The victim was treated and released at a hospital, police said. Late Tuesday afternoon, officers tracked down Humud to arrest him.
Humud was represented by The Legal Aid Society of Nassau County, which has a policy of not commenting at the arraignment stage of a case.
Police said the box cutter and the victim's property have not been found.
Detectives ask anyone with information about the robbery to call 911 or Crime Stoppers at 800-244-TIPS.
