Three people are in police custody after an ex-Portsmouth player told an undercover reporter he had been involved in fixing football matches.
Sam Sodje was filmed by the Sun on Sunday describing how he punched an opponent in a League One game to get a red card in exchange for £70,000.
Former Portsmouth manager Guy Whittingham said in the cold light of day "you can not fathom out why he has done it (punched a fellow player)".
