When you have a suspect restrained nearby, press B then choose Cuff. Cuffed suspects open your Interact, then Suspect options.

On duty, B (or D-pad down) also sets GPS to a dispatch hotspot when no cuff or pickup prompt is in the way. Cuff still wins if a suspect is in range.

Choose Arrest on a cuffed suspect to start transport. Stay close. If the arresting officer leaves range, the suspect sees RUN!!! and can break free.

From Interact, then Suspect you can Frisk suspect and Seize illegal items. Use that to clear guns and contraband before or after an arrest.

A cuffed suspect can open Bribe officer and offer cash (preset amounts). You choose Accept bribe or Reject bribe. Accepting has roleplay and risk consequences. Rejecting keeps the arrest path open.
