Explosives In Storage Unit Unrelated To Bucks Co. Blasts: ATF

The discovery of possible explosive devices at a Bethlehem storage facility is not connected to the series of mysterious blasts that are currently under investigation in Bucks County, according to authorities with the Bureau of Alcohol, Tobacco, Firearms and Explosives.

"We do not believe they are connected," said ATF spokeswoman Charlene Hennessy.

The possible explosives were discovered Wednesday afternoon at Dreamers Self Storage, the Morning Call reported. Residents were asked to leave the immediate area so investigators could enter the facility and examine a “potential explosive device," the report said.

The news comes as authorities are investigating more than 20 unexplained explosions in Bucks County since April.

The latest happened a week ago off in Milford Township, after a tractor rolled over an unknown device while mowing grass. It was the first of the chain of blasts to go off during the day; most have been overnight.

The FBI, Pennsylvania State Police, and the ATF are involved in the investigation into the unexplained explosions, which have baffled and scared residents in Upper Bucks County for two months now.
