ANN ARBOR, MI - A small fire in the basement an office building caused smoke and fire damage Thursday, Dec. 22 on South Main Street in Ann Arbor.

At about 7:40 a.m. Ann Arbor Fire responded to 450 S. Main St. for a fire alarm, said Battalion Chief Derek Wiseley.

There was a small fire that had been smoldering in a lower office unit, he said.

It caused fire damage in that unit and smoke damage throughout the building, which houses Fitzgerald & Associates, Inke's Skin Care, Finn-Tec Oy Computer Repair and Healing River Therapy Massage and Sound.

Firefighters had the fire out quickly, Wiseley said, and cleared out the building with fans.

The cause of the fire remains under investigation, he said.

Ann Arbor Police and Huron Valley Ambulance assisted at the scene.

Main Street was closed from abut 7:45 a.m. to about 8:30 a.m.

The building once housed a Central Intelligence Agency recruiting office that was damaged in a dynamite bombing on Sept. 29, 1968, according to Ann Arbor News records.

From 1968 to 1970, three Ann Arbor buildings were bombed, and members of the White Panthers were indicted. The U.S. Justice Department later dropped the charges, the Ann Arbor News reported in 1972.
