PHOENIX -- A Phoenix man was arrested Tuesday on suspicion of conspiring to commit bestiality after seeking a horse on Craigslist.
Maricopa County Sheriff's animal crimes detectives began investigating 22-year-old Donald Waelde after a Craigslist user reported an ad posted in the website's Missed Connections section earlier this month.
Waelde allegedly stated in the ad that he wanted to "play with a horse" and offered to "do something in return" if he could have access to one.
During the investigation, Waelde allegedly told sheriff's deputies the sex act he wished to perform on the horse and agreed to meet an undercover detective Tuesday in Anthem. The detective brought a mounted posse horse as a prop.
Waelde was taken into custody after reportedly admitting to placing the ad and stating his intentions to carry out the sex act.
Deputies also executed a search warrant at his West Union Hills Drive home in Phoenix.
Since 2011, suspects in four bestiality cases in Maricopa County have used Craigslist to find animals, Sheriff Joe Arpaio said in a statement.
The sheriff's office said Craigslist CEO Jim Buckmaster has not responded to letters from Arpaio asking the company to crack down on postings about illegal activities.
Arizona passed a law in 2006 making bestiality a crime.
