Boston University police arrested one man on Sunday after he was caught allegedly carting two guns outside of the school’s commencement. According to the Suffolk District Attorney’s office, Andreas Massa, 28, was carrying two loaded handguns with high-capacity magazines.

Massa’s wife, Sally, told CBS that she and her husband had just gotten their gun licenses and did not know they were not permitted to carry them on private property. The police stopped Massa after he turned away from the ceremony upon discovering people were being searched. According to Sally, her husband told the police he was carrying weapons when he was stopped.

The couple was at the ceremony for a relative’s graduation.

Colin Riley, a BU representative, told The Boston Globe that Massa “was arrested on his way into commencement; they have a security checkpoint and he was found with two weapons.” He went on to add that the school has implemented increased security measures since the Boston marathon bombing last April.

“All students, faculty staff, volunteers, guests and vendors will be subject to screening when entering any commencement weekend venue, possibly with a metal-detecting wand,” BU said on its commencement website.

20,000 graduates and visitors were expected to attend the ceremony, at which Mass. Gov. Deval Patrick spoke.

Massa is expected to be arraigned by the Brighton District Court on Monday.
