A man who identified himself as an Uber driver was arraigned Tuesday on charges that he robbed and assaulted a woman who had called him for a ride the night before in Malden.

Wilson Brea, 21, of Revere, pleaded not guilty in Malden District Court to assault and battery on a person over age 60 or a disabled person, causing injury, and larceny over $250, court officials said. He was ordered held on $500 bail and is due back in court Sept. 20, Middlesex District Attorney Marian T. Ryan’s office said.

Brea’s lawyer, Kelly A. Norton, said her client “is eager to address these charges’’ and “denying the facts’’ laid out by prosecutors.

Ryan’s office said the incident occurred around 7:40 p.m. on Prentiss Street after the woman, who had used Brea’s services before, bypassed a ride-sharing app and called him directly. Brea asked to use her bathroom when he arrived, and after he exited the restroom he “allegedly took the victim’s handbag,’’ the statement said. “When the victim attempted to stop the defendant from taking her possession he allegedly pushed the victim . . . ’’

He identified himself as an Uber driver when he was arrested, Ryan’s office said. However, an Uber spokeswoman, Susan Hendrick, said Tuesday that the company had no record of anyone by Brea’s name “driving on the [company] platform last night.’’

Hendrick said she did not know if Brea had driven on the platform previously. Some media reports indicated he may have driven for another ride-hailing company, but that Florida-based outfit said it offered no services in Massachusetts.

Ryan’s office identified Brea as “an Uber driver’’ Tuesday.

Brea’s arrest came after Everett Mayor Carlo DeMaria sent a letter on Monday to Uber CEO Travis Kalanick, requesting a meeting after Uber driver Paul J. Griffin, 28, was arraigned on charges of exposing himself to girls in Everett and Malden. He also faces a similar allegation in Boston. None of Griffin’s alleged victims were his passengers during the incidents.

Earlier this month, another Uber driver, 34-year-old Darnell K. Booth, was accused of assaulting a 16-year-old Everett girl he met while driving for the company, despite a criminal history. Uber said company officials are looking forward to meeting with DeMaria. Uber has banned Booth and Griffin from its platform.

Uber says it runs criminal background checks on all new drivers and rescreens them twice a year. New state regulations requiring the Department of Public Utilities to conduct separate background checks of drivers have not taken effect, DeMaria said. The regulations are due by November 2017.
