6:20 p.m. update: A RideAustin driver accused of raping a female passenger in the back of his car last summer had no previous history of criminal activity and passed fingerprint-based and social security-based background checks, officials with the local ride-sharing nonprofit said Monday evening.

No criminal records were found for the accused driver, 40-year-old Osmani Limonta Diaz, in public records independently consulted Monday by the American-Statesman, either.

When Austin police notified RideAustin of the June 10 incident, CEO Andy Tryba reached out to authorities to assist in the investigation, Ride Austin officials said in a statement Monday.

"No person should ever have to experience sexual assault," Ride Austin said in a statement. "The safety of Ride Austin riders is our number one priority. ... Though the incident was still under investigation, Ride Austin deactivated (the driver) from the RideAustin platform as well as proactively notified the other rideshare platforms that the driver was known to work. RideAustin will continue to use both of these, as well as expand our female-only driver options (an option for women riders to request only women drivers)."

It was not immediately clear what other ridesharing companies Limonta Diaz might have worked with. A Fasten spokeswoman declined to say whether he worked for Fasten, citing the company’s driver terms and conditions.

Uber and Lyft did not immediately returns emails Monday night asking whether he worked for them.

Osmani Limonta-Diaz

Osmani Limonta Diaz, 40, has been charged with sexual assault. He was booked Friday into the Travis County Jail, and was in custody there on Monday with bail set at $40,000, jail records show.

According to an arrest affidavit, the woman told police that she had used the RideAustin app on June 10 to request a driver to take her to her Central Austin home. She showed police the app, which displayed details of the trip, including the driver’s name, Osmani, the affidavit said.

She told police she got into the rear passenger seat and the two drove off to her home, where the driver stopped outside her front door. In the affidavit, the woman told police that the driver then turned around and told her he was going to have sex with her.

The driver got into the back seat with her and the two fought before he raped her, she told police in the affidavit. During the attack, the affidavit said, he wore a condom and told her "no one will believe you."

The woman said in the affidavit that after the assault, she got out of the car but couldn’t find her house keys and knocked on the door until her brother let her inside the home.

Her brother called police, who later confirmed the identity of the driver with information provided by RideAustin, the affidavit said.

Investigators interviewed Limonta Diaz, who denied ever having a sex in his car, the affidavit said. "Never," he told police, adding that he has good ratings and is married.

According to the affidavit, Limonta Diaz denied any knowledge of the reported attack and could not explain to investigators how his DNA appeared on the woman’s body.

Police said he suggested to them that the woman was trying to make him her victim.

After investigators obtained a DNA sample from Limonta Diaz through a search warrant and compared it to DNA found earlier on the woman as evidence, they said the samples matched Limonta Diaz’s DNA profile, the affidavit said.
