Warrington Township Police have issued an arrest warrant for a man in connection with the discovery of three pipe bombs in a Bucks County home.
Police say John Grzyminski is cooperating with authorities and is waiting for his lawyer before turning himself in.
Investigators tell NBC10 Gryzyminski's mother found one of the suspicious devices in the kitchen of her home and called police.
Warrington Police, the Philadelphia Bomb Squad and ATF agents arrived and detonated the pipe bombs. The bombs were then sent to a lab in Washington, D.C.
Investigators did remove other items from inside the home, which belongs to the suspect's mother, including several riffles.
The bomb discovery forced the evacuation of several homes along Saddle Driver near Carriage Way around 4:30 p.m.
"It's really scary, you think you live in a safe neighborhood," a neighbor tells NBC10.
Gryzminski is facing multiple charges including possessing or manufacturing weapons of mass destruction, risking a catastrophe, posession of an instrument of crime and recklessly endangering another.
