Anna Tang, the Wellesley College student accused of sneaking into her ex-boyfriend’s MIT dorm room and stabbing him while he slept, was arraigned Monday.

The 20-year-old student pleaded not guilty, and Judge Linda Giles ordered her held on $100,000 bail with surety or $10,000 cash bail alternative with the condition of house arrest and GPS bracelet monitoring, according to the Middlesex County District Attorney’s office.

Tang, who originally is from Indiana, faces charges of home invasion, armed assault with intent to murder and assault and battery with a dangerous weapon causing serious bodily injury.

According to the Middlesex County DA’s office, a security guard let Tang into her ex-boyfriend’s dorm room at 500 Memorial Drive at 6:30 a.m. Oct. 23; she then stabbed him seven times while he slept.

Police found the victim in his room bleeding from multiple stab wounds. The victim told police he awoke to find Tang on top of him, stabbing him repeatedly, according to police reports.

Police later found Tang in the dorm building, her jacket covered with blood and a black folding buck knife in her backpack. Prosecutors alleged that in the days leading up to the attack, Tang purchased knives and a crossbow pistol.

The victim was transported to a Boston hospital, where he was treated for his injuries and released.

Tang was a summer student at the Surgical Planning Laboratory at Brigham and Women’s Hospital, according to a Harvard Web site. Before her arrest, she was completing her bachelor’s degree in computer science at Wellesley College and had been working at MIT’s Department of Computer Science.
