BOSTON (WHDH) - An MIT student who allegedly entered a dorm room at Boston University and sexually assaulted a woman has  pleaded not guilty to on rape charges.

Samson Donick, 20, formerly of Boston and now of Tiburon, California, was charged with aggravated rape, breaking and entering at night with the intent to commit a felony and indecent assault and battery. He is a basketball player for MIT.

On Oct. 18, police said Donick and three other men were signed in to a Boston University dorm by two female students at around 2 a.m.

At around 2:30 a.m., Donick and one of the men left the suite in search of a specific woman known to the second man, police said. For about 30 minutes, Donick and the other man entered 10 different dorm rooms on four different floors. During that time, prosecutors said, the 20-year-old victim awoke to find Donick in her room sexually assaulting her. Police said the victim did not know Donick or the second man. Donick allegedly ran out of her room when she screamed.

The victim told Boston University Police and the college issued a public safety alert. Numerous students began reporting that two unknown college-age men had entered their dorm rooms during the time in question.

Boston University Police later recovered surveillance camera footage depicting the two men in a building stairwell and got their identification from the desk where they had been signed in. They were identified and the second man gave a statement indicating that he and Donick had entered several suites and bedrooms during that time, including one bedroom in which Donick had stayed for a short time.

Donick was arraigned on Wednesday and pleaded not guilty to all charges.

He was held on $10,000 cash bail.

He was ordered to surrender his passport, have no contact with the victim or witnesses, stay away from the BU campus and remain outside of Massachusetts should be post bail.

He is due back in court on June 22, with a trial date of Feb. 8, 2017.

MIT refused to issue a statement and only said that Donick is not currently registered at the school.
