Boulder police are looking for a tall young man who escaped capture while “covered in feces” after he contorted himself inside a portable toilet at the Hanuman Yoga Festival Friday.

A woman had gone inside to use the toilet when she suspected someone was hiding in the well-used bowl beneath a tarp, police said today.

A security officer waited outside until a shirtless, shoeless man came out stained with human waste. When the officer tried to stop him, he made a run for it and got away.

Witnesses told police he might be a local transient who uses the name Sky.

He is described as white, about 20 years old, between 6 feet, 4 inches and 6 feet, 8 inches tall with a thin build and short, dark hair.

Witnesses said he had cuts on his back and legs and was wearing leather bracelets on each wrist.

Anyone with information can call Detective Jeremy Frenzen at 303-441-1890 or Northern Colorado Crime Stoppers at 1-800-222-8477 or 1-800-444-3776.

There is a $1,000 reward.
