WASHINGTON (CBSDC/AP) — An activist who posted a video of himself loading a gun in D.C.’s Freedom Plaza will remain in jail while he awaits trial on gun charges.

Adam Kokesh of Herndon, Va., appeared Monday in D.C. Superior Court for a detention hearing and was denied bond by a judge who called him a “very dangerous person,” according to media reports. Kokesh, a 31-year-old former Marine, is charged with one count of openly carrying the weapon in violation of District of Columbia law.

Court documents allege that on July 4, he went to the city’s Freedom Plaza and publically loaded four rounds of ammunition into the weapon. A video of him loading the gun posted on YouTube lists “Adam Kokesh” as the video’s source.

He faces up to five years in prison and/or a fine of $5,000 if convicted.

Kokesh’s attorney said he needed to speak to his client further before talking with the media.
