ROANE COUNTY, Tenn. — Federal authorities are investigating after one person was injured in an explosion at a scrap metal recycling yard in Roane County.
The Knox County Sheriff's Office said its explosives unit was called to assist after an explosion was reported at PSC Metals outside Harriman.
KCSO said one person was hurt in the explosion and taken to an area hospital but did not know that person's condition.
A company spokesman for PSC Metals issued the following statement about the accident: "Earlier today, we had a small explosion at our automated teller machine located at our Harriman, Tennessee facility. The cause of the explosion is unknown. We have temporarily closed the facility while authorities investigate the matter. Our employees, suppliers and customers are our number one priority."
On Friday, officials said the person who was injured was not an employee at the scrapyard.
According to the Roane County Sheriff's Office, the Bureau of Alcohol, Tobacco, Firearms, and Explosives is leading the investigation into the incident.
Certified explosives specialists are on the scene working with KCSO and others.
The ATF said personnel will be on the scene for at least the next couple of days to determine what happened, saying they are checking to see if any type of explosive or explosive mixture was used. It is also checking to see if the explosion could have been caused by a device or pyrotechnics, such as fireworks.
