A six-month long undercover sting has led to the arrests of 62 drug dealers –some of whom peddled crack, cocaine and heroin near public schools in Queens, authorities said today.

The suspects, ranging in age from 16-to 62-years-old, were busted after selling tens of thousands of dollars worth of drugs to undercover police officers in building lobbies, near schools and in commercial parking lots in Jamaica. There were 33 sales that took place near M.S. 72 on Guy R. Brewer Boulevard, P.S. 123 on 119th Avenue and John Adams Annex-Jump Start Academy on 141st Street.

Many of the thugs also operated out of the Baisley Park Housing Development and Rochdale Village, but most of them did not live there.

Officers allegedly netted 60 pounds of marijuana, $30,000 and seven weapons after executing 14 search warrants. They also seized six cars.

“While dealers have frequently attempted to use public housing as a convenient marketplace, law enforcement will persist-as it did in this case-in jailing them, especially when they sell near schools,” said Police Commissioner Raymond Kelly. The defendants are charged with criminal sale of controlled substance, criminal possession of a weapon and criminal sale of a weapon. Some of them face up to 25 years in prison.

The perpetrators were members of nine crews, which were loosely affiliated with each other.
