Dylan Napa took the extraordinary step of removing his pants in front of a Bulldogs official this week to prove he was not the person at the centre of yet another lewd video doing the rounds on social media.

Napa went out of his way to show he did not have any tattoos on his upper thigh, proving rumours he had again been caught on camera were nothing more than a case of mistaken identity.

Napa fronted the media for the first time on Wednesday to speak about the number of sensational videos that first surfaced last month and which now threaten to see him suspended from the opening rounds of the NRL season.

The Canterbury forward said he had no idea who had leaked the footage, which was taken around five years ago, and he did not know whether more videos would make it to the public domain.
