The son of a West Ham fan who died after collapsing at a football match has offered a reward for the return of his father's beloved Rolex watch. Kevin Gray, 61, from Suffolk, collapsed and died watching West Ham play in London on 9 December. His son Jamie Gray, 31, said his family enquired about his father's belongings after his death but realised the watch — which was a gift from friends for Kevin's 40th birthday — was gone. Jamie said his family are willing to pay £2500 to anyone who "anonymously wants to drop it off... no questions asked. "We just want it back."
