Norwich have made a formal complaint to police over alleged racist tweets directed at defender Sebastien Bassong.
The Canaries confirmed they had passed on evidence to Norfolk Constabulary which was supplied to them by supporters in the wake of Saturday's Barclays Premier League draw at Everton. Press Association Sport understands Norwich have sent police screen-grabs of tweets that have since been deleted from Twitter accounts that no longer exist.
Manager Chris Hughton told a press conference on Monday it was "hugely disappointing" to learn of the alleged abuse of Bassong, who scored a stoppage-time equaliser in the 1-1 draw at Goodison Park. He added of the tweets: "We have taken the appropriate action and passed them on to police."
