Hello, I was the staff member who issued the ban.
First of all you got banned for Leaving to Avoid Roleplay, you were being chased by the MOI, you were shot in the process so they ran into the ICC to detain you, you went and purchased some stuff from the vendor in the BB after that you went to the front entrance of BB once you were right next to the door you saw that the NSB general and his men were running towards the BB and the second you saw them running towards you, you left, after which NSB-Generalinspektor made a ticket asking if you had left the game as they were searching for you and as I saw you leave as they were running to the BB I claimed the ticket and took action.
As usual the final decision is up to the UA but to summarise my reasoning, you saw MOI coming to take you so you left the game to avoid roleplaying with them.
