A MetroAccess driver was arrested Sunday on charges that he sexually assaulted a customer.
Kingston is employed by Challenger Transportation, a subcontractor of MV Transportation, the contractor that provides MetroAccess service. Metro said contractors provide their own background checks on drivers, not Metro.
The victim alleged that Kingston sexually assaulted her Aug. 27 in Montgomery County.
MetroAccess offers transportation services to people with special needs who cannot use bus or rail.
Several other alleged incidents have been reported this year.
In July, a Regency Cab driver was accused of sexually assaulting a female passenger using MetroAccess services.
In April, a contract driver for MetroAccess was arrested and charged with sexually assaulting a female customer in January -- about two months after another driver was fired for a similar incident.
