NASHVILLE, Tenn. (AP) Tennessee state authorities said Wednesday they are investigating the company that owns a plastics factory where 11 workers were swept away by cataclysmic flooding unleashed by Hurricane Helene.

As the nearby Nolichucky River swelled from rainfall, employees in the Impact Plastics factory in Erwin, a small community in rural Tennessee, kept working. Several asserted that they werent allowed to leave in time to avoid the storms impact. It wasnt until water flooded into the parking lot and the power went out that the plant shut down and sent workers home.

Several never made it.

The raging waters swept 11 people away, and only five were rescued. Two of them are confirmed dead and are part of a toll across six states that has surpassed 180. Four others in the factory are still missing since they were washed away Friday in Erwin, where dozens of people were also rescued off the roof of a hospital.

Tennessee Bureau of Investigation spokesperson Leslie Earhart said Wednesday that the agency is investigating allegations involving Impact Plastics at the direction of the local prosecutor.

District Attorney Steven R. Finney said in a statement that he asked the bureau to look into any potential criminal violations related to the occurrences on Friday.

Impact Plastics has not been contacted by the TBI yet but will fully cooperate with their investigation, said the companys spokesperson, Tony Treadway. He said the company is preparing an internal review which it will release to the public.
