Christo claimed that he had spied on women in other public restrooms around Boulder. Detectives are contacting business owners in an attempt to substantiate Christo’s claims and searching those restrooms.

Detectives have already confirmed there are peepholes in the restrooms of several local businesses. Owners are sealing those holes. Police are not releasing the names of the businesses while the investigation is ongoing.

Christo was arrested on charges of unlawful sexual contact and criminal invasion of privacy, related to the yoga portable toilet incident at the Hanuman Yoga Festival in Boulder on June 17.

That day, a woman who went into the toilet said she noticed something moving inside the tank when she lifted the lid. A man she asked to check reported seeing someone covered in a tarp inside the tank.

The man told police he walked outside and heard the toilet door lock from inside. A festival security supervisor waiting outside said a man eventually emerged and he chased him.

But the suspect, described as covered in waste, slipped away.
