Michael O'Neill, the Wheatfield man involved in an explosion July 21 at a Walmore Road garage, was remanded to federal custody during a detention hearing Wednesday in U.S. District Court.
O'Neill, 45, has pleaded not guilty to possession of an unregistered destructive device. The charge carries a maximum penalty of 10 years in prison and a $10,000 fine. He was officially arraigned on the charges July 27.
Investigators said they found an area in the garage in which explosives were being manufactured, with explosive powder and BBs in plain view. The bomb squad also discovered what appeared to be seven improvised explosive devices and other items.
O'Neill is now at a rehabilitation facility after his leg, injured in the accident, was amputated. A preliminary hearing is planned for Aug. 18 in federal court.
