— An air traffic controller at Charlotte Douglas International Airport was arrested in Charlotte Friday after investigators alleged he was in possession of a "weapon of mass destruction."

Officials have learned the weapon was a homemade pipe bomb.

According to the Federal Bureau of Investigation, 30-year-old Paul George Dandan is currently being held in the Mecklenburg County Jail under a $45,000 bond.

The FBI said they are assisting Charlotte-Mecklenburg Police with their investigation and that they don't anticipate federal charges.

Detectives learned that 39-year-old Derrick Fells, Dandon's roommate, built the explosive device. He admitted to detectives that he made the bomb in order to use it against a neighbor.

Dandon, who was an air traffic controller, only had access to the offsite air traffic control tower and could not access any restricted areas of the terminal or ramp.

Fells was charged with three counts of manufacturing a weapon of mass destruction and one count of possession of a weapon of mass destruction.

Dandon was charged with possession of a weapon of mass destruction, acquiring a weapon of mass destruction and transporting a weapon of mass destruction.
