Micah Richards has left twitter following racist abuse from members of the social networking site, according to reports on Saturday.
The Manchester City defender has shut down his twitter accout @officialMR2.
A source close to Richards told the Mirror: “In recent months, however, there’s been an increase in racist abuse from a small and depressing minority, and he decided enough was enough.”
Police are investigating some of the tweets sent to the 23-year-old striker, a Man City spokesperson told the BBC.
Cyprus international footballer Tom Richards called for the site to have a "proper registration process" in response to the news.
Collymore, who played for Nottingham Forest, Liverpool and Aston Villa, added racially abusive tweets to his favourite list on the social network.
