Two Vineyard Haven men were arrested in Oak Bluffs on Friday afternoon after they were found with a quantity of drugs, including heroin, marijuana, hashish and prescription drugs, police said.

Oak Bluffs police arrested Jeffrey Sylvia, 23, and Jeffrey Rancourt, also 23, both of Vineyard Haven, at about 2 p.m. Friday in the Our Market parking lot, where they were in Mr. Rancourt’s pickup truck. “The two men had arrived to make a drug deal,” a press release from the Oak Bluffs police said.

Police seized 28 grams of heroin, three and a half ounces of marijuana, one and a quarter ounce of hash, five tablets of suboxone and other prescription drugs, two cell phones, two digital scales and a box of plastic bags and rubber bands.

Mr. Sylvia was charged with trafficking in heroin, possession of marijuana with intent to distribute, possession of hashish with intent to distribute, and possession of class B and class E drugs with intent to distribute.

Mr. Rancourt was charged with knowingly being present where heroin is kept and conspiracy to violate drug laws. Both men were transported to the Edgartown house of correction on Friday afternoon where they posted bail and were released; arraignment was set for yesterday morning in Edgartown district court.

Oak Bluffs police Lieut. Timothy Williamson said yesterday that police made the arrest acting on information, and that the location of the bust was incidental. “[The parking lot of Our Market] is not a magnet for drug deals. They happen all over town,” he said.
