FAIRFIELD — An anonymous tip led to the arrest of two suspected drug dealers and their customer last Friday.

Police said a “John Doe” called police to report he believed illegal drug deals, involving a Roselle Street resident, were being transacted on the street several times a week. The deals, he said, regularly took place about the same time and involved a silver car.

Officers set up surveillance in the area, and around 6:30 p.m. Friday, a man — later identified as Nicholas Bandanza, 20 — was seen walking down the street. He was met by a silver Honda, driven by Javier Rodriguez of Bridgeport.

Police said they saw a “hand to hand” transaction, before the car drove off. While one officer detained Bandanza, a second patrol car followe the Honda, and turned on the lights and sirens in an attempt to pull the car over. A short, low-speed pursuit followed until the Honda stopped on Euclid Avenue.

Javier Rodriguez, 28, of Park Avenue, Bridgeport, allegedly admitted to police that he had sold drugs to Bandanza, according to the report, but said he only sold him “a dime bag of weed.” However, police said they found 10 wax folds of heroin in Bandanza’s pocket.

Police found marijuana and $635 in cash hidden in Javier Rodriguez’ pants, while Christian Rodriguez, 22, of Dover Street, Bridgeport, a back seat passenger in the car, was also had marijuana, police said.

Both Bridgeport men were both charged with sale of narcotics and conspiracy to sell narcotics, and released after posting $10,000 bonds. Bandanza was charged with possession of narcotics.
