A Bucks County man is facing weapons of mass destruction charges after authorities said they found a large bomb at his Milford Township property Thursday. The bomb, which was "ready to be detonated," has been seized by authorities, said Bucks County Attorney General Matthew Weintraub.

David Surman Jr., 30, was arraigned Thursday in connection with the bomb, which was discovered during an extensive federal and state investigation into a series of explosions across the county since early April. He is being held at Bucks County prison on $750,000 bail. A preliminary hearing is scheduled for July 10, court records show.

In addition to the large bomb, other explosive devices and "many, many" chemicals capable of making bombs were located at Surman's property. Items seized during the raids will be sent to the FBI facility in Quantico, Va. to be analyzed, Weintraub said.

It is not clear what Surman intended to do with the bombs.

Surman is facing four felony counts of possessing/manufacturing weapons of mass destruction, as well as four counts of possession of an instrument of crime and four counts of prohibited offensive weapon, among other charges.

The following image of the bomb seized by authorities was released by the Bucks County District Attorney's office:

In addition to the bombs and chemicals, officials said they located a notebook with odd sketches depicting everything from swastikas to gravestones and cartoon images of bombs going off.
