The betting syndicate is very powerful and is easily capable of getting Majid to make the tape to get the players in trouble.
They could threaten him or pay him to make this video.
It's the players who have their career's to lose,not him. Don't think if nobody incurred a straight loss on this ,he can be charged with anything serious at all.
Let the police first establish the date of the video through forensics and other stuff before coming to conclusions either way.
Prima facie it may seem evidence but it is not the case many times once examined thoroughly.
