The Martha’s Vineyard Drug Task Force arrested an Oak Bluffs man this week on charges of cocaine trafficking.

Gizmar DeSouza, 28, was arraigned Feb. 20 in Edgartown district court on charges on trafficking in a class B substance (cocaine) and unlicensed operation of a motor vehicle. Police said he allegedly had 28 grams of cocaine in his possession.

Oak Bluffs police Lieut. Tim Williamson said the arrest was the result of an ongoing drug investigation by the task force. On Tuesday, Feb. 18, the task force initiated a traffic stop at the roundabout.

Lieutenant Williamson said Mr. DeSouza was found to be in possession of “a fairly large quantity of cocaine,” as well as a scale and packaging materials.

He said Mr. DeSouza had a total of more than 28 grams of cocaine, and police also seized $3,277. Lieutenant Williamson said the police are looking to keep the money through asset forfeiture. Bail was set at $7,500, and Mr. DeSouza is also being held on an Immigration and Customs Enforcement (ICE) detainer. A pretrial hearing was scheduled for April 11.
