A Portsmouth man pleaded guilty Thursday to assaulting a fellow passenger with a dangerous weapon on a cruise ship last year.
Michael Truman, 39, will be sentenced on August 29. He faces a maximum penalty of 10 years in prison.
According to court documents, Truman assaulted a passenger aboard the Carnival Magic cruise ship on Oct. 20.
The cruise ship was off the coast of Nantucket in open waters.
Truman was loudly disrupting a theater show aboard the cruise ship when he was asked twice by a fellow passenger to quiet down. After Truman refused, the passenger began to leave the area to request assistance from a cruise ship employee.
Truman then smashed a cocktail glass into the victim’s face, got on top of the victim and began striking him further. The broken glass caused significant lacerations to the victim’s face requiring more than a dozen stitches.
