WATCH: Woman coughs on Uber driver then attacks him after he asks her to put on a mask

In a video posted to Twitter by Dion Lim of ABC News 7, a young woman can be seen coughing in an exaggerated manner on an Uber driver, then grabbing his phone and snatching his mask from his face as she assaults him from behind.

The driver, 32-year-old Subhakar Khadka, told CBS San Francisco that he believes he was attacked he is a South Asian immigrant.

"I never said anything bad to them, I never cursed, I was not raised that way. I don't hit people, I am not raised that way, so they were not getting out of my car," said Khadka.

As Lim wrote on Twitter, "Uber driver Subhakar told me he picked up 3 women in the Bayview yesterday & after asking one to wear a mask was subject to slurs, taunting & one grabbing his phone. He's taking a few days off. SFPD is investigating."

After the altercation, Subhakar held up his mask, showing it was unusable because one ear-strap was broken as the woman repeatedly cursed him and called him a "b*tch' while her companions laughed and stared at their phones.

One woman sprayed pepper spray into the car after leaving the vehicle, according to police.

In a separate Tweet, Uber responded to the report saying the woman has now been banned by their company.
