in the arrest of Wong Po. Ma then catches Chan's team's in the act of murdering the henchman that actually killed the undercover agent. Ma briefly fights the four of them. The group receives a message warning them against leaving the police station that night. Ignoring the threat, Lok goes to buy a gun to serve as Wong Po's "murder weapon", but is trapped in an enclosed area and ends up getting killed by a knife-wielding Jack. Meanwhile, a copy of the original video tape is given to Chan's superior, Cheung Chun-fei. Seeing that Chan had tampered with evidence to frame Wong Po, Cheung releases Wong and tries to arrest Chan.
