Forest Grove police fielded three calls about a masked man holding an American flag and wearing a gun strapped to his hip downtown Saturday afternoon, according to the department.

Between 1:10-2:30 p.m., police received the calls about the man, who was at Main Street and Pacific Avenue, said Capt. Mike Herb, a Forest Grove police spokesman. The man, Herb said, wore a V-for-Vendetta mask.

Police responded, Herb said, and the man refused to speak with officers. He appeared to take photographs of the police response with a cellphone.

Herb said officers determined the man was likely exercising his Second Amendment rights. Officers reportedly watched him but did not stop or detain him.

"We did not determine him to be a threat to the extent that he did not have his gun out pointed at anyone," Herb wrote in an email. "It goes without saying folks were alarmed by his actions."

Several people also reportedly took photographs and video of the man.
