A manager at Laugh Factory Chicago was arrested by masked federal agents … and, the wild encounter with law enforcement was caught on video.

Night manager Nathan Griffin was arrested Friday morning outside the club … and, the clips shows officers slamming him to the ground while onlookers scream hysterically.

Griffin was ultimately subdued and thrown into the back of a white SUV while people demanded to know where the masked agents were taking Griffin.

According to the local NBC affiliate in Chicago, a Border Patrol spokesperson told them Nathan “attempted to impede and obstruct federal officers” after they say Griffin tried to shut a door of the federal agents’ car on an agent’s leg.

A GoFundMe posted by Nathan’s brother-in-law for legal fees claims he was detained for four hours before he popped up in FBI custody … and, he could face years in prison if convicted.
