NEW YORK (AP)  -- The former head of a notorious street gang that peddled more than $100,000 worth of drugs out of a Staten Island housing project was among three suspects arrested after an eight-month undercover sting, police said Thursday.

Tender Dixon, 29, faces charges of selling three weapons to undercover officers. Until a recent demotion, Dixon had been the head of the Staten Island faction of the Latin Kings, a group that also included his uncle Juan Negron and 18-year-old Michelle Farless who were arrested with him.

All three were scheduled to be arraigned Friday on charges including gun sale and drug trafficking, and criminal possession of a weapon, prosecutors said.

Messages left for Dixon and Farless' attorneys were not immediately returned. Negron didn't have a lawyer yet.

Police were still looking for two other suspects. Police Commissioner Raymond Kelly and District Attorney Daniel Donovan noted that the suspects came from the same housing development where Detectives Rodney Andrews and James Nemorian were slain in 2003. The undercover officers were shot in the head by Ronell Wilson, who climbed into the back seat of their unmarked car on the pretense of selling them an illegal gun. Wilson was sentenced to death for the murders.

``Hundreds of times undercover officers pose as criminals in order to document illegal gun sales,'' Kelly said. ``The fact that we continue to do whatever it takes to get guns off the street is a fitting memorial to Detectives Andrews and Nemorian.''
