The muslim guy's name is adnan he resides in UAE, he comes on a chatroom and abuses sikhs many times. A few days ago he posted this link in the chatroom showing him and his friends making fun of sikhs and physically slapping an innocent sikh bother.
Adnan and his gang caught this singh after a cricket match he was on his own, while adnan was with his thugs. They took the mick out of him, but the singh is likely to get away lightly they could have done worse.
