UPDATED 2 p.m. ET: This article has been updated to include details about the victims and suspect. 

Tufts University in Medford, Massachusetts, was locked down Sunday morning after two people were stabbed at a fraternity house, the Boston Globe reported. Police searched the area for the attacker or attackers, telling students and staff members to remain indoors during the search.

Police brought a person of interest into custody on Sunday afternoon, Boston TV station WCVB reported. The person of interest is a Tufts University student. The victims -- a 19 year old Boston man and a 20 year old Boston man -- were not students at the university and suffered non-life-threatening injuries, the station reported.

Following the stabbing at about 5 a.m. EDT, students and staffers were told to “shelter in place” and keep doors locked.

The lockdown was lifted at about 8 a.m. but authorities warned that a large police presence would remain. The university posted on its Twitter account:


Tufts representative Kim Thurler told the Associated Press that the stabbing occurred in Delta Tau Delta fraternity house on Professors Row, which traverses the Medford/Somerville campus. The fraternity house remains blocked off with police tape, the Boston Globe reported. A private university located about five miles north of Boston, Tufts has a student body of more than 10,500.

“The victims are not affiliated with Tufts University,” the school said in a statement. Both were taken to an area hospital, it said. There was no information released about the condition of the victims, WHDH-TV reported.

Police are interviewing witnesses and looking for those with details about what happened.

In recent months, incidents at fraternity houses have gain increased scrutiny across the country. A Pennsylvania State University fraternity was suspended after revelations that members had posted pictures of women, some nude, on a secret Facebook page. A University of Oklahoma fraternity was kicked off campus following the online publication of a video of its members singing a racist chant. And both questions and a lawsuit remain about what happened to a Clemson University fraternity pledge who died while on a morning run with other members of his group.
