A gang of six teens decided to take Grand Theft Auto IV from the television screens to the streets of Long Island, with a two-hour crime spree meant to copy the game’s violent hero, cops said.

The game-crazed youth’s real-life robbery romp featured such staples of the mega-popular game as a mugging, several break-ins and an attempted car-jacking at an intersection in tony Garden City, police said. “They decided they were going to go out to commit robberies and emulate the [lead] character Nico Belic in the particularly violent video game Grand Theft Auto,’ said Nassau County Police Detective Lt. Raymond Cote. “These teens have difficulty separating fact from fiction, fantasy from reality . . . It was quite alarming.’

The rampage started at 11:30 p.m. Tuesday, when four of the teenagers – Brandon Cruz, 15, Gurnoor Singh, 14, Samuel Philip, 16, and Jaspreet Singh, 17, – were sitting in Memorial Park in New Hyde Park looking for something to do, cops said.

Cops said that they decided to act out the game, in which players live out the life a Belic, an Eastern European criminal who uses murder and robbery to rise to the top of the underworld in “Liberty City,’ which bears a close similarity of New York City.

“They were bored and they decided this was a good idea,’ Cote said.

According to cops, the boys first mugged a man at a bus stop near the park, beat him and knocked out some teeth. They then broke into some sheds and garages, stole some bats and crowbars and met up with a few more teens to continue the spree.

The six then attempted to stage some carjackings in Garden City. But it was game over when one of their would-be victims – a 23-year-old woman in a 2008 BMW – called the cops, who quickly arrested them.

All four of the original teen plotters were arrested, along with the two youths who joined them, Stephen Attard, 18, of New Hyde Park and Dylan Laird, 17, who was visiting Long Island from Southborough, Mass. They were all charged with first-degree robbery, except for Jaspreet Singh, who was charged with possession of stolen property. The other charges were pending.

Police would not say specifically how they knew that the teens crimes were motivated by Grand Theft Auto, and not by some other motive. They said they discovered it during their investigation.
