A shocking video has emerged of a Tube passenger standing up to a man in the middle of an allegedly homophobic rant after New Year’s Eve celebrations. <br /> <br />Ryan Mahon was travelling on the Northern Line in the early hours of New Year’s Day, when he saw the man ‘shout abuse at a drag queen’. <br /> <br />After stepping in, Ryan was himself targeted with abuse and violent threats. <br /> <br />‘Had an amazing night celebrating New Years with great people!!’ he wrote in a Facebook post. <br /> <br />‘Unfortunately, on the way home I witnessed an absolute idiot shouting abuse at a drag queen on the tube.’ <br /> <br />After Ryan got involved, the aggressive passenger shouted at him: ‘If there was no camera nowhere, you’d have no jaw.’
