An American Uber passenger is livid after having to share his journey with an unknown woman, apparently intoxicated, who performed oral sex on the driver while the car was in motion.

Bostonian Aner Manuel was so appalled by the incident, which took place in Chicago, that he filmed and uploaded it to various social media channels, prompting a refund of $10 (£7.50). He feels the sum is insufficient.

"F**k Uber for providing me with the most unsafe and dangerous ride home last night. This driver had a random prostitute in the front seat," wrote Manuel on Twitter on 17 July.

In a later post, made on Uber's official Facebook page, the stylist went into more detail about the trip. He said:

"On Sunday July 16th I received the most dangerous and inappropriate uber ride ever. As I approached my Uber, I noticed there was a passenger in the front seat.

"I double checked to make sure I didn't select UberPool, and then approached the car. I assumed it may have been a family member of some sort.

"As we pulled off the female in the front (who was clearly on drugs) attempted to open the door and could not even sit straight as the vehicle was in motion.

"She then began to grope him and grab him. They began to kiss and she began loosening his belt. As we got further and further from my pickup location I had no idea where I was, so I had to stay in the car.

"She then proceeded to perform oral sex. This was my last straw. I asked the driver to drop me off. Since I've contacted Uber and they refunded me for trip and gave me a $10 credit."

"They've seen this video and are still 'investigating'. They have been extremely bad at answering any messages I've sent, and I demand something gets done. This is not okay!

A spokesman for Uber told Gizmodo: "The behavior of this former driver is appalling and is not tolerated on the Uber app. As soon as this situation was reported to us, we immediately removed this driver's access."
