Is Police Tactical Unit coming back?

At the heart of the action is the Mobile Unit, an elite tactical team within Rongcheng's Criminal Investigation Division. Crime scenes are their domain, for example, a meticulously staged celebrity suicide, a masterfully planned heist, a perfectly concealed drug den, a cop ambush laced with traps, and so on. Criminals may set elaborate decoys, but they are no match for the detectives' sharp eyes.
