An MIT student wearing what turned out to be a fake bomb was arrested at gunpoint Friday at Logan International Airport and later claimed it was artwork and that she was there to meet her boyfriend, officials said.

Star Simpson, 19, had a white computer circuit board and wiring over a black hooded sweat shirt she was wearing, said State Police Maj. Scott Pare, the commanding officer at the airport.

"She said that it was a piece of art and she wanted to stand out on career day," Pare said at a news conference. "She claims that it was just art, and that she was proud of the art and she wanted to display it."

Simpson was charged with possessing a hoax device. A not guilty plea was entered at her arraignment in East Boston District Court and she was released on $750 bail.

She could face up to five years in prison or a $5,000 fine, if convicted.
