AN investigation into racist abuse against former Forest star Stan Collymore (pictured) on Twitter has ended, he has said.
Staffordshire Police launched an inquiry after the footballer turned pundit was targeted on the social networking site in January.
But he has said the investigation has finished because the force cannot get hold of "user information".
He tweeted: "Cannock and Staffordshire Police have been exceptional. It's Twitter refusing to give info. Twitter, beyond UK law. For now."
Collymore received the abuse after he suggested Liverpool striker Luis Suarez cheated by diving during a match against Aston Villa.
A spokeswoman for Twitter said it could not comment on individual accounts "for privacy and security reasons".
