An open-carry activist has sued two Forsyth County (Ga.) Police officers who arrested him at a park, after a confrontation with a private security guard.

Christopher Proescher was stopped by private security officer Reid Hanna on April 20, as he walked in Sugar Hill's Gary Pirkle Park with his Smith & Wesson M&P pistol. Officers Adam Bell and Rodney Dantzler responded to Hanna's call of a suspicious person.

The officers arrested Proescher on suspicion of criminal trespassing. Proescher filed a federal lawsuit against Hanna, Bell, and Dantzler individually, reports the Atlanta Journal-Constitution.
