Uber is in trouble once again.

A woman passenger in Delhi has accused an Uber driver of sexually assaulting her while driving her to Gurgaon. The woman's brother lambasted Uber, an app-based taxi service, in a Facebook post that has been shared several hundred times, NDTV reports.

"My sister availed your cab service, last night for Gurgaon & your driver Vinod tried to kiss her forcibly & even after registering complaint with you morons there has been no action, no update form your end," said the woman's brother in his Facebook post, that drew comments of outrage against Uber, which was banned for a short while in Delhi last year after one of its drivers allegedly raped a woman passenger.

Uber said in a statement posted as a comment to the Facebook post that "immediate action has already been taken" against the driver, even as it investigates the complaint.

In December last year, a 27-year-old finance executive of a Gurgaon-based company alleged that the driver of an Uber cab drove her to a deserted place after she fell asleep in the vehicle and raped her. Uber's service was suspended for some time.
