A Massachusetts Institute of Technology student who was arrested at Logan International Airport in September for wearing what the police initially mistook for a bomb has apologized for her actions, The Boston Globe reported today.

The local district attorney dropped the only criminal charge — possession of a hoax device — against the student, Star Simpson, who will be a junior at MIT this fall. A judge ordered her to offer the public apology and to perform 50 hours of community service with students and veterans, the Globe reported.

Ms. Simpson, from Lahaina, Hawaii, studies electrical engineering and computer science at MIT. At the time of her arrest — at gunpoint — she was wearing a sweatshirt adorned with a circuit board, green LED lights, and wires connected to a nine-volt battery.

“Although I never intended to act in a disorderly fashion, I now realize that the shirt I created caused alarm and concern at Logan Airport,” Ms. Simpson said in a written statement. —Sara Lipka
