PORTLAND, Ore. (KOIN) — A Portland man has been charged for forcibly assaulting and intimidating a federal worker near the Mark O. Hatfield Federal Courthouse, U.S. Attorney Billy J. Williams announced.

On August 24, Dakota Kurtis Means allegedly began following an employee around 5:30 a.m. while yelling obscenities. Court documents say he was carrying a black paintball rifle and told the employee “it’s a paintball gun now, but it’s going to be an AR later.” U.S. Marshals Service deputies arrested the 20-year-old a short time later.

Means was charged with forcibly assaulting, impeding, and intimidating a federal employee while engaged in or on account of the performance of their official duties — a Class A misdemeanor punishable by up to one year in federal prison.

He pleaded not guilty at his first court appearance on the same day as his arrest. A one-day jury trial is scheduled to begin on October 27.
