Originally formed only to patrol the People Mover, the Transit Police began DDOT patrols in March 2014, in response a spike in crime on buses. As of May 2022, the Transit Police no longer conduct regular patrols on the People Mover, with the DTC instead contracting with private security firms for People Mover patrols; they initially hired Detroit-based City Shield Security Services, before switching to Securitas in April 2023.
