An eccentric man with a clinical history of histromania, a psychological compulsion to play various theatrical roles in daily life. He treats the world as his stage, bringing ordinary people into his unscripted performances without their knowledge.

He serves as an assistant during an initial interrogation, displaying extreme nervousness about both the angry public outside and the unpredictable behavior of the suspect inside. He worries constantly about keeping his pension safe and strictly follows his superiors' orders.

A subordinate policeman present during the fateful fourth-floor interrogation of a suspect. He actively participates in fabricating new versions of the official police report, offering absurd details to explain away inconsistencies. He operates as a willing, somewhat clueless participant in the department's collective fictions.

A rank-and-file officer who briefly enters the second-floor interrogation room. He tries to navigate the chaotic environment created by a suspect who barks contradictory orders at him regarding keys, eventually reminding his superior of a scheduled meeting.
