Drunk PAX
I heard the same from a local FO that it is true, and the Captain is already back on the line after 2 weeks of unpaid vacations.
Apparently there is more to the story; ground staff and Cabin Crew did not want to deboard the PAX and so the Captain made the decision on his own.
It is right though, the FOM does mention the moment responsibility is transferred to the Pilots at the moment the doors are closed. Thats why you see them bail almost instantly upon arrival 😆
But there must be a moral of the story if something happens...
