Portland police said they responded to 911 calls about two men in a car with an assault rifle near the Burnside Bridge around 7 p.m. Wednesday and arrived to discover 13 members of a club for bearded men wearing military camouflage on the bridge, KPTV, Portland, reported Thursday.
Two of the men were holding onto an assault rifle and were arrested on disorderly conduct charges. The other men were detained and released.
The men told KATU-TV, Portland, they were on their way to shoot a photo for the breast cancer awareness calendar "Beards for Breasts."
"We didn't mean to shake up the community or shut down the Burnside Bridge," club member Matthew Jenkins said. "Just trying to save boobs, you know?"
Police said the bridge was reopened after about an hour.
