Two area men were arrested last week on charges of selling heroin to Darien residents in the northwest section of town near Stamford, according to police.

Police developed leads that one of the men, Joshua Sanchez, 24, was expected to come from his home city of Waterbury to Darien to deliver heroin to town residents.

On the night of Aug. 20, undercover officers, detectives and a K-9 Unit set up surveillance of the 500 block of Hoyt Street close to the Merritt Parkway to intercept Sanchez, according to police.

Just before 11 p.m. police saw a car driven by Sanchez traveling south on Hoyt, and based on their information stopped his car in the area of Leeds Lane, according to police. In the car was a second man identified as Roberto I. Cales, 24, of Seymour.

Police found more than 110 bags or wax folds of heroin in Sanchez’s possession, as well as $255 in U.S. currency, according to police, and Cales was found to have 4.9 grams of marijuana.

Sanchez, of Day Street in Ansonia, was charged with possession of narcotics and possession of narcotics with intent to sell, according to police.

Cales was charged with possession of narcotics, possession of narcotics with the intent to sell, and possession of marijuana, according to police.

Both men were released on $50,000 bond each and are to appear in state Superior Court in Stamford on Monday, Aug. 31.
