Former footballer Stan Collymore has accused Twitter of not doing enough to combat abusive messages after he was targeted by internet trolls.
Mr Collymore said he received offensive messages and death threats after he suggested Liverpool striker Luis Suarez dived to earn a penalty in last Saturday's match against Aston Villa.
