Story update

The 53-year-old Bloomfield Hills resident's pickup slid into a ditch along the highway, and for unknown reasons he exited the and began shedding articles of clothing while walking along the congested highway in a snowstorm, said Auburn Hills Police Lt. Casimir Miarka.

"He didn't appear to be injured and he was cooperative," Miarka said. "We don't know why he was doing what he was doing. The original calls we received just said he began stripping his clothes and walking near the highway there."

Police transported the man to an Auburn Hills fire station. From there, he was transported to the hospital for examination.

A motorist caught a portion of the odd ordeal on video with his cell phone and posted it to YouTube.

A man, "roughly 50 to 60 years old, was walking on 75 freeway in the City of Auburn Hills Michigan during a blizzard," wrote the YouTube user, Francis Gojcaj, in the video description. "Yee haw cowboy lol."

The man recording the footage yells, "Hey," but the naked man offers no response and continues walking down the center of the highway in the direction of flashing police lights.

Another motorist, who exited his vehicle to check on the situation, stops to talk to the man capturing the footage.

"He's opened up car doors," says the passerby. "Look at him walking in the road. Look at the truck. His truck is over here, his clothes are all the way down the road.

"I just didn't want him to open a car door full of family or something, you know what I mean?"

Miarka said the investigation is not completed, but no citations were issued and a warrant review request has not been submitted to the Oakland County Prosecutor's Office.
