Recently a player in the ongoing Malaysian Chess Festival, who shall go unnamed, was caught with a phone on his/her person.

That person's game was immediately forfeited because this is a clear vioaltion of the rules of the tournament. No chess program can be found on the phone so the case is not a proven cheating case. However the player was suspended from the tournament because did not comply with surrendering the phone immediately and instead was possibly deleting apps before finally giving the phone up.

Of course FIDE or the person's chess federation will have to investigate and make some decision if further punishment is needed.

If it's a proven case of cheating the punishment will be a 3 to 5 year ban from all tournaments.
