#Naked man spends night atop railroad crossing sign, punches K-9 after chase, cops say

An Oregon man spent an entire night perched naked on top of a railroad crossing sign then jumped down, led cops on a wild chase — and punched a police dog, according to authorities.

Brandon Lee Jackson, 39, allegedly bared his own caboose during the odd ordeal — at points exposing himself and tossing objects at onlookers — starting at around 9 p.m. Monday night in Eugene, police told the CBS affiliate KVAL.

He allegedly spent more than 12 hours sitting on the sign in his birthday suit while cops blocked off nearby roads and sent crisis negotiators to try to talk him down, the station reported. During the incident, he allegedly “struck a male victim in the head with a rock,” police said.

After Jackson finally hopped to the ground in the pouring rain, he tried to make a break for it, prompting police to unleash a police canine — which he allegedly slugged several times, according to the station.

Video footage shows at least four police officers chasing after Jackson and taking him into custody. He was charged with assault, reckless endangering, criminal trespass and criminal mischief.

His condition, and what may have prompted the loco-motive moves, weren’t immediately clear.
