An Air Force sergeant who was on the Vineyard in August as part of the protection team that travels with President Obama is facing assault charges in Edgartown district court in connection with a Saturday night bar fight.

At a show cause hearing set for Nov. 2, the district court clerk magistrate will consider charges of indecent assault and battery on a person over 14 and assault and battery against Master Sgt. Peter McNally, 41, an explosives ordnance device expert and resident of Florida. Mr. McNally was on the Vineyard as a member of the so-called bomb squad employed to protect the President, police said.

The incidents took place on August 27 at the Wharf Pub in Edgartown and the nearby Atlantic bar when Mr. McNally allegedly groped a woman at the Wharf and punched a manager at the Atlantic. The manager, Jamie Zambrama, 55, is also facing assault charges after he allegedly struck Mr. McNally repeatedly.

According to the Edgartown police report, Mr. McNally was at the Wharf drinking that night and at some point was asked to leave. He then went across the street to the Atlantic where he became involved in the altercation with Mr. Zambrama. Edgartown police, who were already on the scene that night for another, unrelated call, found Mr. McNally on his hands and knees, bleeding from the head. Several witnesses reported seeing Mr. McNally punch Mr. Zambrama and the manager’s subsequent alleged retaliation. Mr. McNally was transported to the Martha’s Vineyard Hospital for treatment. The following day a woman who had been in the Wharf that night with her boyfriend filed a formal complaint with police saying that Mr. McNally had groped her inappropriately earlier in the evening.

Both men have been issued summons to appear in district court for hearings to consider the charges.
