Police responded to a potential bomb threat in downtown Bluefield, West Virginia, according to reports.

Reports say a loud boom could be heard outside the federal courthouse after a police bomb squad yelled “Fire in the hole!” Bluefield Police Chief Dennis Dillow told reporters that three suspicious devices had been found inside the courthouse early Monday morning, prompting a police response, according to the Bluefield Daily Telegraph. 

“We are in the middle of investigating this,” Dillow told the outlet.

A bomb squad from nearby Charleston arrived soon afterward, and the devices were detonated at 11:40 a.m., according to the Telegraph. No smoke or debris was reportedly visible, indicating a controlled detonation.
