A Massachusetts man is being held without bail after allegedly bringing guns and ammunition to his dorm room at MIT.

The Middlesex District Attorney's Office says 23-year-old Angel De La Cruz had a dangerousness hearing Friday after he was arrested last Friday evening by Massachusetts Institute of Technology police.

Police had received a tip that De La Cruz had firearms in his possession on campus, and when they searched his dorm room, they found a rifle, a pistol and illegal large-capacity ammunition that hewas not licensed to carry or possess, according to the district attorney's office.

De La Cruz was arraigned on Monday on multiple charges, including two counts of carrying a dangerous weapon on school grounds and two counts of possession of a firearm without a license.

It's not clear whether De La Cruz has an attorney.

MIT police said De La Cruz was not violent when he was arrested and there is no evidence there were any threats made toward the MIT community.

An MIT spokeswoman said the school is not commenting on the case because it is still under investigation.
