Former England striker Stan Collymore calls on Twitter to take "more responsibility and action" after being subjected to racist abuse on the social media site

Former footballer Stan Collymore has accused of Twitter of putting profits before social responsibility by "not doing enough" to combat abusive tweets after he was targeted by internet trolls.

Police confirmed they are investigating a series of offensive messages directed at the ex-England striker, which were sent after he suggested Liverpool striker Luis Suarez cheated by diving during last Saturday's match against Aston Villa.

Collymore retweeted some of the abuse he has received since the match, three days ago, as he called on Twitter to take action.

He wrote: "In the last 24 hours I've been threatened with murder several times, demeaned on my race, and many of these accounts are still active. Why?

"I accuse Twitter directly of not doing enough to combat racist/homophobic /sexist hate messages, all of which are illegal in the UK."

Speaking to ITV News, Collymore said that "Twitter seems to be living in its own bubble at the moment. If somebody passed my line of sight now and called me some of the abuse and the threats that I've had in the last 24 hours, they would be arrested, so why not on social media?"
