A man who apparently desired to ambush police was killed Tuesday inside a plasma donation center in southwestern Michigan during a shootout that injured an officer, authorities said.

A Kalamazoo officer was shot in the upper body, but his injury wasn’t life-threatening due body armor that he was wearing, said Karianne Thomas, the city’s public safety chief.

Another officer fired multiple rounds and killed the suspect, Thomas said. The name of the decedent wasn’t immediately released, Fox News reported.

Lisa Walterhouse, an employee at the downtown plasma center, says police responded after the man entered the building and fired shots. As a result, she said he urged staff to call 911.

He “wanted to ambush officers. … The suspect was waiting by the door for officers to arrive,” Thomas said. “They encountered gunfire and returned gunfire.”

No other injuries were reported. Thomas said the officer who repeatedly shot the suspect has been with the department for less than a year.

“We are not immune to workplace violence or violence directed at our first responders,” the chief said.
