Several fire crews in South Bend are working to extinguish a fire at Fun F/X on Sample Street Friday evening.

The fire is in a three-story warehouse in an industrial area west of Chapin Street. It broke out some time around 4:20 p.m.

Firefighters on the scene say the fire was on the second and third floors and coming through the roof, which has begun to fail.

Employees reportedly were in the building when the fire started, but everyone was able to escape.

"We had one that was in the basement that smelled smoke and the other one smelled smoke. They started exiting the building pretty much at the same time," Captain Gerard Ellis said.

Ellis said no one was injured.

One woman said she saw smoke all the way from Portage Road.

"A big cloud of smoke came up from behind the tree," Bryanna Redmond said.

Significant smoke resulted in limited visibility, and traffic was blocked off all night. People are encouraged to avoid the area to allow firefighters to work.
