MARYVILLE, Mo. — Shots were fired during the night on the campus of Northwest Missouri State University but no one was injured, school officials said Sunday.
No one had been arrested. Officers were looking for two men they described as persons of interest, but said they believed the men had left the campus.
Campus safety officers and local police searched the campus from room to room, university officials said.
The campus-wide alarm system was activated, warning all students, faculty and staff to take shelter. The lockdown was lifted by Sunday but university officials said authorities were ''maintaining a high level of awareness.’'
The gunshots were reported late Saturday, shortly before midnight, near The Station, a conference and activity center on campus, a university statement said.
It was not immediately clear how many shots were fired.
Maryville is about 90 miles north of Kansas City.
