Part of the roof at a Knox County factory collapsed after heavy rain early Thursday night, injuring a number of people, authorities said.
Initial reports indicated some people were trapped in the building. But WYM-TV at Hazard reported that three people were injured that all had been removed from the wreckage.
Knox County officials could not be reached by phone for comment Thursday night, but Kentucky State Police at Hazard confirmed the incident.
The collapse occurred about 8:30 p.m. at Tru Seal Technologies Inc., a firm that makes insulating glass sealant.

Authorities said the collapse was believed to have been caused by water pooling on the roof from heavy rains.
The National Weather Service at Jackson said parts of Knox County received 2 to 3 inches or more of rain from a thunderstorm that moved through the area around 7:45 p.m. Thursday.
Weather service officials said those hurt in the roof collapse did not appear to be seriously injured.
