BROOKLYN - The main art building at Brooklyn's Pratt Institute was engulfed by a four-alarm fire overnight.

According to the FDNY, flames ripped through the top floor of 200 Willoughby Ave. in Clinton Hill at around 2:00 a.m., causing the roof to partially collapse. About 200 firefighters responded and several were taken to the hospital with minor injuries.

A faculty member says the building houses the president's office on the lower level and art classrooms on the upper levels. He says it's a big setback for a university that's already strapped for space.

The cause of the fire is under investigation, but officials say it doesn't appear to be suspicious.
