BOULDER, Colo. (CBS4) – A Boulder park is back open after a scare closed it Tuesday morning when people reported seeing a man with a gun.

After an intensive search police found the man in Chautauqua Park.

Police and canine units and sheriff’s deputies combed Chautauqua Park beginning at about 9 a.m. That’s when deputies got a call about a suspicious man wearing camouflage gear heading up a trail. It appeared he looked like he was hiding a weapon under a blanket.

Deputies eventually found the man early in the afternoon below the first Flatiron.

“They found him with a gun, but nobody was injured and he was cooperative when they located him,” Heidi Prentup with the Boulder County Sheriff’s Office said.

The gun was described as a .22 caliber air rifle commonly used for target shooting or small game.

Deputies say while it is illegal to bring a gun into Chautauqua Park, the man won’t be facing any charges as he’s being held on a mental health evaluation. His name hasn’t been released.
