[Mr. Plow]

Cutler?

A volunteer at Denver's Municipal Animal Shelter has been suspended and Denver police are investigating claims he was caught in sexual behavior with a dog at the shelter.

"We had an incident," Doug Kelley, director of the shelter, confirmed to CBS4's Brian Maass. "Police are investigating allegations of misconduct by a volunteer. A person has been suspended from being a volunteer."

Kelley said the incident in question occurred Saturday at the shelter and police interviewed shelter employees Monday about what happened.

Kelley declined to provide further details except to say, "There was no apparent injury to the animal."

Kelley said the volunteer could potentially face animal cruelty charges.

Several other sources familiar with the incident said a shelter employee saw the man behind the building engaging in what appeared to be sexual contact with a dog. The volunteer was reported to be at least partially naked.

Denver's Municipal Animal Shelter has about 45 volunteers.

District attorney's spokeswoman Lynn Kimbrough said her office in investigating and called it "a serious accusation."
