Washington police were called to Lions Lake early Monday morning because of a report of a naked man swimming in the lake.
According to Det. Sgt. Steve Sitze, when officers arrived they found a man who was wet, shirtless and appeared to be intoxicated.
Police said he told them he was taking part in the Polar Plunge. Investigators say the man told a witness earlier that he was going streaking.
Sitze said the man was taken to the police station and placed in protective custody. Police did not release his name.
