Multiple people were injured in shootings that took place at Michigan State University on Monday night, officials said. After the first shots were fired, students and staff at the school were ordered to “secure-in-place,” authorities said.

“There have been shots fired near Berkey Hall on the East Lansing campus,” MSU police wrote on Twitter. “Please secure-in-place immediately. Police are active on scene,” the post continued.

Authorities said that the suspect, who was on foot, was walking around the campus. The second shooting took place at IM East, a gym on campus.

Blake Maday, a Michigan State University student on campus, said that students were sheltered inside.

“Everyone is barricaded in their places with lights out,” Maday told Fox News Digital. “Students are sending in all types of reports and it seems like people are sending the police on a wild goose chase with nothing confirmed.”

This is a developing story.
