Police investigating a possible break-in at a rock museum were surprised when they stumbled upon a man concealed on the ground by a moss-like camouflage outfit.
Sgt David Thompson of the Washington County Sheriff's Office said the hidden suspect cried out when a search dog bit him before dawn outside the Rice Northwest Museum of Rocks and Minerals, near Portland, Oregon.
Police say the man was wearing a "ghillie" suit, a camouflage outfit designed to resemble heavy foliage.
Police identified the man, dubbed "Moss Man" on the internet, as 36-year-old Gregory Liascos of Portland. They arrested him on burglary and criminal mischief charges.
Sheriff's officials said nothing was stolen.
They said Liascos cut a hole in a museum wall and was trying to gain entry.
