UPDATE, Oct. 28, 2:40 p.m.: Connecticut woman who fired warning shot at man allegedly sexually assaulting pit bull will not face gun charges »

WATERBURY, Conn. — A 22-year-old Connecticut man was taken into custody on Tuesday morning after a bizarre incident in Waterbury where he was allegedly found raping a woman's pit bull in her back yard.

According to the New Haven-based ABC affiliate WTNH, the dog's owner, Alice Woodruff, allegedly found a completely naked man sexually assaulting her dog on Tuesday around 10 a.m. Woodruff told the news station that her dog, which she described as an aggressive rescue dog kept tied to an 800 pound tow chain, was surprisingly calm during the incident.

"He pranced through the yard naked, yelling ‘this is our day and you have to prosper in it. ISIS sent me,'" Woodruff told WTNH. "I was thinking ‘did something like this just land in my back yard?’ I ran in, got my gun out of the bedroom."

The woman said she fired a warning shot into the ground but the man, unaffected by the gunshot, then began walking toward her. He was apparently yelling about the end of the world and saying he gave her dog Ebola, according to the Hartford Courant.

As police arrived at Woodruff's home, the man reportedly fled and several subsequent 911 calls reported a naked man running through back yards in the city's Bunker Hill neighborhood. He was eventually caught and believing he was suffering from some type of mental breakdown, the man was taken to St. Mary's Hospital where he remains under psychiatric evaluation.

Declining to release the man's name, police say he will face charges including fourth-degree sexual assault, cruelty to animals and second degree breach of peace when he is released from St. Mary's.
