A man called dispatch tonight saying he had a gun and was headed for the Fargo police department.
Police responded to the call about 10 p.m. when the man arrived at the police department on a bike.
Sgt. Carlos Nestler said the man wasn't actually armed but was upset over a previous incident with officers.
The man complied with police after about 5 to 10 minutes and was taken into custody.
Nestler said the incident is under investigation, and police will determine whether or not the suspect will be arrested or charges will be filed.
