Two docked for allegedly calling policeman thief

It sounds like there was a situation where two individuals were docked (likely meaning they were punished or penalized in some way) for allegedly making a statement that a policeman was a thief.

Can you tell me more about what happened? What was the context of the situation, and what was the nature of the alleged statement made by the two individuals? Was it a verbal altercation, a written statement, or something else?
