Undercover Child Sex Sting Leads to a Police Chief's Arrest

The online ad was pretty blunt: "Dominate [sic] male police officer seeks fun, discreet, sub playmate -- m4w."

Before long, that officer got a response from a purported 14-year-old girl. And the age didn't dissuade him, authorities said.

"... everyone has to have a first time," the officer responded, according to a criminal complaint. "... you will just have to get me naked tomorrow."

But the officer sending those crude messages wasn't just any cop -- he was Michael William Diebold, the police chief of Leechburg, Pennsylvania, investigators say.
