Students and staff of The Catholic University of America were ordered to shelter in place for a portion of Wednesday afternoon as police searched for suspects in an armed robbery.
The shelter-in-place order was cancelled after less than 30 minutes, according to the university's Twitter account.
"Shelter in place. This is not a drill. Details to come," the university told students.
D.C. police searched for suspects near the north end of the campus, on John McCormack Drive NE, about 4:15 p.m., the university said. School security officials saw the police activity and notified the school communications center, which issued the shelter-in-place order.
One suspect was arrested. After the second suspect was arrested, school officials lifted the shelter-in-place order about 4:40 p.m.
"Whenever a threat is perceived, #CUA follows operational procedures which prioritize the safety of the community," the university tweeted.
No additional information was released immediately.
