When they got there, they say their investigation found that 32-year-old A.R. Caruana had been pointing a gun and making threats.
Caruana was arrested and taken to the Wake County Jail.
The chief said Caruana was off-duty at the time of the incident and his service weapon was not involved.
Caruana joined the department on June 4, 2000, holds the rank of senior officer, and has most recently been assigned to the department's Gang Suppression Unit.
Police say the dispute that led to the charges was a domestic related incident and not related to Caruana's law enforcement duties. The investigation continues.
