Bridgeton, MO (KMOV) — A man is facing charges for allegedly making pipe bombs in Bridgeton, Missouri.

Police allege 44-year- old Douglas Herr of Springfield, Illinois bought a pipe 1.25 inches in diameter from a Home Depot in Bridgeton, Mo. on April 13.

Herr allegedly asked the staff at Home Depot to cut it into 7.5 inch sections with each end threaded for a cap.

Home Depot employees became suspicious and called police. Officers said they eventually executed a warrant at Herr’s hotel room at a Super 8 and found materials for making a pipe bomb such as 25 pounds of gunpowder, pipe end caps and fuse wire.

Investigators did not mention what Herr planned to do with the pipe bombs. A spokesperson for the FBI said they do not have credible threats for any local targets, including Busch Stadium or Lambert Airport, which is only three miles from where Herr allegedly stored the bomb making material.

Herr is charged with unlawful possession, transport, manufacture, repair or sale of an illegal weapon.

Herr was arrested and is being held at the St. Louis County Jail on a $250,000 cash-only bond.

Police also said Herr is currently on probation for two separate crimes, including a robbery of hundreds of dollars of Mama Lucia’s frozen pizzas from Wentzville, Missouri. Court documents say Herr was supposed to be supervised by the mental health caseload and subject to drug and alcohol treatment.
