Fort Worth police say an Uber driver is wanted for the alleged sexual assault of a 77-year-old passenger last month.

Hashem Ramezanpour, 40, faces a warrant for aggravated sexual assault, police said Monday.

Ramezanpour is accused of stopping his 2016 white Honda Civic while en route to the woman's residence in Fort Worth and assaulting her on Sunday, Oct. 22.

The Uber driver was taking the woman home after she attended church in Dallas.

She told Fort Worth police the assualt happened in "a dark, wooded area" of Highway 377 in North Fort Worth, only minutes from her home.

After she was sexually assaulted, the woman says Ramezanpour drove her the rest of the way home.

Police believe Ramezanpour may have fled the country, but they ask anyone with information on his current whereabouts to contact sex crimes investigators at 817-392-4350 or 817-392-4359.

Police said as a safety precaution, they recommend anyone using a paid private transportation service to not ride alone.

In a statement to NBC 5, an Uber spokesperson said: "What has been described and reported to police is a violent act no person should ever have to go through. We are working with law enforcement officials to fully support their investigation. This former driver's access was immediately removed from the app and he has been permanently banned."
