Several people were injured Monday due to shots fired on the campus of Michigan State University, school police said.
University police noted on Twitter that there appeared to be a single suspect, described as a “short man with a mask” and who remained at large.
“We continue to receive multiple calls of an active shooter on campus,” it noted.
At least five victims were at Sparrow Hospital, said hospital spokesman John Foren, who did not provide information on their conditions.
Authorities ordered students and staff members to take shelter after reports of gunfire around Berkey Hall, an academic building on the East Lansing campus, shortly after 8:30 p.m.
The alert advised students and staff to “immediately shelter in place” and to stay tuned to alert.msu.edu for information.
By 10:15 p.m., police said Berkey, as well as nearby residences, were secured.
Separately, police reported a shooting at IM East, a student recreation center.
Aedan Kelley, a student who lives less than a mile away from the campus, said he locked his doors and covered his windows “just in case.” The sound of sirens was constant, he added, and a helicopter flew overhead.
“It’s all very scary,” Kelley commented. “And then I have all these people texting me asking if I’m OK, which is overwhelming.”
Michigan State University has 50,000 students. East Lansing is located about 90 miles (145 kilometers) northwest of Detroit.
Meanwhile, the East Lansing High School auditorium, where a school board meeting was being held Monday night, was locked down and police prevented people from leaving, the Lansing State Journal reported.
