Police on Monday night reported “multiple injuries” and issued a shelter-in-place order at Michigan State University, following reports of gunshots fired on campus, according to Twitter posts from the department.

The shots were fired near Berkey Hall on the East Lansing campus, the police said. Later Monday night, police said there was “another reported shooting at IM East. Police are responding. There are multiple reported injuries.” 

In an update, police said IM East was being “secured” and that “it appears there is only one suspect at this time.”

In an earlier Twitter post, the MSU Police and Public Safety department said had warned that “the suspect is believed to be on foot right now.”

“Community members on and off campus should continue to shelter in place. Police are continuing to respond,” the post added.

An alert sent shortly after 8:30 p.m. local time urged people to “run, hide, fight,” according to CBS Detroit.

In a Twitter post, Michigan Gov. Gretchen Whitmer said she had been “briefed on the shooting at Michigan State University.” 

“The Michigan State Police along with MSU Police, local law enforcement and first responders are on the ground,” Whitmer said. “Let’s wrap our arms around the Spartan community tonight. We will keep everyone updated as we learn more.”
