BOULDER, Colo. -

A Colorado man who hid in the tank of a portable toilet at a yoga festival to spy on women has been sentenced to three years in prison and 10 years of probation.

The sentence for 31-year-old Luke Chrisco was handed down Friday in Boulder. He pleaded guilty in July to two burglary counts and attempted unlawful sexual contact.
    
Police arrested him in 2011 after a woman at a yoga festival in Boulder noticed something moving in the tank of the portable toilet, then saw a feces-stained man emerge and run away. Police said he also was suspected of hiding in other bathrooms around Boulder to watch women use the toilet.
    
KUSA-TV reports that prosecutors dropped other burglary charges and a misdemeanor count of criminal invasion as part of a plea agreement.
