He was arrested. The Star-Ledger has the details:
According to the arrest warrant, Simpson on June 24 created a “risk of (serious) bodily injury to the passengers onboard New Jersey Transit Bus 8097, specifically by removing his hands from the wheel and masturbating while continuing to drive in traffic.”
He was driving the No. 116 bus route between Carteret and New York at the time. His bail was set at $2,500.
