( Delhi Twp ) - Police had been looking for the man who's been trying to rape women in Hamilton County since April of 2012.

Hamilton County Prosecutor Joe Deters named 39-year-old Tony Pippin the so-called "Delhi Rapist" in a news conference on Monday. Pippin's under indictment on 21 counts including aggravated burglary, attempted rape, robbery, felonious assault, rape, sexual battery, unlawful sexual conduct with a minor, receiving stolen property, and more.

Investigators say in April, August, and September of 2012, Pippin targetted women at the Knotty Pine Bar in Colerain, and followed them home to rape them. In at least one case, the woman was able to fight Pippin off.

Pippin's also accused of drugging and having sex with an underage teen girl in November, 2012, allegedly taking video of the crime on his cell phone.

The Hamilton County Prosecutor says some of the most compelling evidence came from tony Pippin, who volunteered DNA, because he thought he was going to become an undercover informant.  Deters says they matched that to DNA from the first rape.

Pippin was arrested in December, after he allegedly assaulted a man and a woman at a bar in Colerain Township.  Deters says that altercation started when people at the bar accused Pippin of being the Delhi Rapist, and ordered him out.  "They were right," said Deters.

If he's convicted on all 21 charges, Pippin could get up to 100 years in prison.  But Deters says he wouldn't be surprised if more victims stepped forward, now that Pippin is in custody.
