New York (CNN Business) Nine people were sexually assaulted by "fake Uber drivers" between September 2016 and February 2018 in Los Angeles, a new lawsuit alleges.

The lawsuit is being brought by three of the individuals, all listed as Jane Does, who claim they were raped by individuals who posed as Uber drivers to pick up passengers. It was filed in Los Angeles Superior Court on Friday.

The Jane Does are accusing Uber of negligence, arguing the company failed to warn them and other customers about fake drivers targeting women who were drinking in the area, despite being allegedly warned by law enforcement, according to the complaint.

The suit comes more than a week after University of South Carolina student Samantha Josephson was kidnapped and killed when she got into a vehicle she mistakenly thought was the Uber she ordered.

According to the complaint, law enforcement warned Uber on at least five occasions of assaults by fake Uber drivers within a section of Los Angeles where several popular nightclubs are located. The lawsuit claims the warnings came from the Los Angeles Police Department and the Los Angeles County Sheriff's Department, and took place before the first Jane Doe was allegedly raped on June 18, 2017.
