STOCKERTOWN - Police say a DUI incident led to a bomb scare that shut down Stockertown’s Main Street early Sunday and caused officials to evacuate three homes.
One man is in custody and police are continuing to investigate. Very little information has been released to the public but police say the suspect is not a Stockertown resident.
The incident began with a report of a DUI at 2 a.m. followed by a 3 a.m. report of a possible “dirty” bomb on Main Street. Police have not confirmed the presence of a bomb but did call in Forks Township and Northampton County emergency responders.
Reports around 4 a.m. indicated a suspect allegedly began aiming a "large-caliber gun with a radiological symbol on it" at cars and that the suspect may have "prior operative experience." Police and emergency units limited their radio communication because the suspect reportedly had numerous radios in his possession.
Residents who were told to evacuate their homes have since been able to return, police say. Traffic from Main Street and Route 33 was temporarily rerouted but is now back to normal.
A "dirty" bomb is a mix of explosives such as dynamite with radiological material, according to the Centers for Disease Control. More information is available on their website
