Bomb experts took to a big empty field Thursday afternoon to detonate explosives after a morning long search in Spinnerstown in the wake of more than 20 mysterious explosions that have rocked rural Bucks County for months now.

Authorities arrested 30-year-old David Surman Jr. on weapons of mass destruction and other charges after they descended on a home on Old Bethlehem Pike and another location on Spinnerstown Road with a search warrants. They came here to hopefully end the search for the alleged bomb maker.

Investigators in bomb suits scoured both locations after nearly two dozen blasts rattled the Upper Bucks County area since April. Some explosions left huge craters in the ground. No one was injured, but the explosions had the entire area worried.

The massive search on Thursday focused on a home in the 2400 block of Old Bethlehem Pike in Milford Township and another on Spinnerstown Road where bomb experts and investigators carefully went through the area looking for evidence in the wave of explosions.

The suspect and his girlfriend were questioned in connection with the explosions. She has not been charged. Police say an 18 inch bomb was found during the search Thursday.

David Surman, Jr. is out on bail tonight.
