The billionaire co-owner of West Ham United Football Club has promised to give a homeless man who aided victims of the Manchester terror attack a "life-changing" offer to help him "get back on his feet".

Rough sleeper Stephen Jones rushed to help young victims following the terror attack at an Ariana Grande concert at the Manchester Arena, which left 22 people dead and scores injured.

West Ham's David Sullivan told BBC Radio 5 Live that he wanted to help the "hero" by paying for his accommodation for six months and giving him some money to help him turn his life around.

"It looks like he needs some help, so we are desperate to find who he is and give him six months' free accommodation and a little bit of money to help him on his way," he said.
