Norwich have reported four separate incidents of actual or alleged racist abuse towards their player Sebastien Bassong to police, the club have announced in a statement.
Both South Wales Police and Norfolk Police are now investigating the claims.
A Swansea supporter was released on bail on Sunday after being arrested during Norwich's 4-3 victory on Saturday for allegedly making racist gestures towards Bassong. It is believed the 23-year-old had made gestures towards the player as Norwich celebrated their fourth goal in the game and he was arrested soon after the incident.
