The player was escorted out after witnesses saw him shouting loudly and angrily at a floor person during the early stages of the tournament.
Apparently Demetriou had been playing for some 15 minutes when it was decided to remove four of the stacks from each table, which meant the players would be playing a 6-handed shoot-out. Demetriou felt this was a serious departure from the structure as published and an exchange of opinions with a floor manager took place in which Demetriou protested and asked for a refund on his buy-in.
This was apparently refused and after some argument the manager disqualified Demetriou and had him escorted from the hall.
After a delay of almost an hour, Demetriou finally managed to speak to a senior but unidentified WSOP executive who reconsidered the rules, acknowledged that the eviction had been an error and offered to reinstate Demetriou or refund his buy-in. Demetriou accepted the latter option and departed, but later had a productive meeting with the tournament director at WSOP on improving channels of communication. This resulted in an agreement to introduce a player's consultation booth where players can have issues addressed in a calm and professional manner.
