Richards, 20, is an up-and-coming star of the Premiership nightspot scene, and has so far been awarded 11 drinking-caps for his country. However, it is alleged that on 31 January, Richards participated in a football match against Stoke City.
The shock allegation comes hard on the heels of two further police enquiries about Liverpool and England drinking ace Steven Gerrard and top Brazilian pint-sinker Robinho, both of whom are currently being investigated by police following allegations of football-playing.
Man City Drinking-Club Manager Mark Hughes said, "we are very supportive of Micah, who denies categorically any accusation of footballing. The police are continuing their enquiries, Micah will cooperate fully, and we hope that he will be fully involved in our drinking session with Middlesborough Ravers on 7 Feb.
A spokesman for Greater Manchester Police said, "we can confirm that a 20-year-old man has been arrested in connection with allegations of playing in a football match. The individual concerned has been bailed pending further investigations.
Former top guzzler George Best was unavailable for comment, due to being dead.
