Police officers arrested a 19-year-old student at Boston’s Logan International Airport after she walked into a terminal having a circuit board strapped to her sweatshirt, authorities said.

Star Simpson, a student at the renown Massachusetts Institute of Technology (MIT), walked into the arrivals terminal at Boston airport Friday morning and received information from an airport staffer about an incoming flight.

She was wearing an electronic device with numerous wires on her black sweatshirt. Simpson was also holding Play-Doh, prompting the airport employee to contact police officers and report the device which looked like an explosive one.

The student was surrounded by policemen on a street outside the airport's Terminal C. The law enforcement officers armed with automatic weapons asked her to stop, hold up her hands and make no sudden movements, a police spokesman said.

The woman complied and “ended up in a cell instead of a morgue,” Major Scott Pare said. He added that “deadly force” would have been used to stop her if necessary.

Police discovered that the so-called bomb was nothing but a harmless circuit board with a battery and some lights, charging the MIT student with disturbing the peace and possessing a hoax device.

Simpson claimed the device was “art” which helped her stand out at the university’s career day. She was released on a 750-dollar bail and is expected to face a pretrial hearing next month.
