A North Carolina air traffic controller and another man have been arrested after police found what they’re calling a weapon of mass destruction in the men’s apartment.

Police were originally alerted to the dangerous device when they received a 911 call claiming two men on the 300 block of Minitree Lane had been in possession of a homemade explosive device, WCNC reports. Detectives responding to the call confirmed that Charlotte Douglas Airport’s air traffic controller, 30-year-old Paul George Dandan, and his roommate, 39-year-old Derrick Fells, had a homemade pipe bomb in their possession.

According to reports, Fells originally constructed the device in order to use against a neighbor with whom he had an on-going dispute with. Fells decided not to go through with the plan, however, and instead gave the device to Dandan.

Police have since assured the public that there was never any danger to any incoming or outgoing flights. Dandan’s access had been limited to an offsite air traffic control tower and had no access to restricted areas including terminals or the ramp.

Both men are facing federal charges. So far Fells has been charged with three counts of manufacturing a weapon of mass destruction and one count of possession of a weapon of mass destruction. Dandan is also facing serious charges including possession of a weapon of mass destruction, acquiring a weapon of mass destruction, and transporting a weapon of mass destruction.

At this time investigators have not revealed if the men involved in this case had any intention of actually using the device against the public at large.
