CHARLOTTE, N.C. -- Authorities say an air traffic controller at a North Carolina airport has been arrested on charges of possessing a weapon of mass destruction.

Paul George Dandan, 30, is charged with possession of a weapon of mass destruction, acquiring a weapon of mass destruction and transporting a weapon of mass destruction, CBS affiliate WBTV reports. Police say Dandan, an air traffic controller at Charlotte-Douglas, had a homemade pipe bomb he got from another man, Derrick Fells.

Charlotte-Mecklenburg police said Fells admitted to them that he made the bomb to "use it against a neighbor" with whom he had an ongoing dispute. Fells then changed his mind and gave the bomb Dandan, police said.

The FAA also confirmed to WBTV that they had "terminated [Dandan's] access to the facility and is investigating."
