Firefighting crews responded to a blaze at the historic Maccabees Building on the campus of Wayne State University Wednesday afternoon. Officials say the fire was contained to one floor and there were no injuries.

Wayne State Chief of Police Anthony Holt says the fire broke out from an HVAC unit.

“Investigations still continue,” says Holt, “but it was an electrical fire that began on the 11th floor on a platform outside the building there.”

Officials say most of the building’s damage appears to be water related, caused by the sprinkler system going off. Detroit Fire Department spokesperson James Harris says crews were on the scene in under five minutes.

“The men and women of the Detroit Fire Department did an awesome job,” says Harris, “awesome response time. No one was injured, everybody got out okay.”

The 15-story Maccabees Building is about 100 years old. It was added to the National Register of Historic places in 1983.

The Maccabees is the former home of WDET. The station operated there for more than two decades, moving out in the 80s following an electrical fire.
