( CNN ) -- London police have dropped an investigation into Premier League referee Mark Clattenburg after he was accused of using inappropriate language towards a footballer from Chelsea . The official was the subject of a complaint to the Football Association ( FA ) from Chelsea after their 3-2 defeat by Manchester United in October but vehemently denies their claims . The club claimed Clattenburg used `` inappropriate language , '' thought to be of a racist nature , during an exchange with their Nigerian midfielder John Obi Mikel . Subsequently , the Society of Black Lawyers made a complaint to the Metropolitan police , who now say the probe has been shelved due to a lack of evidence . A statement read : `` An investigation was launched into alleged comments made during a football match between Chelsea FC and Manchester United FC at Stamford Bridge on 28 October 2012 . `` This follows on from a complaint received by the Metropolitan Police Service on 29 October . Enquires were made and no victims have come forward . The matter will remain as a recorded incident . `` Without a victim and/or any evidence that any offence has been committed , the matter can not currently be investigated . `` If the situation changes and a victim and/or evidence to support an allegation of a crime comes to police attention then further enquiries will if appropriate be made . '' Clattenburg has not officiated a match since Chelsea filed their report with the FA , and the 37-year-old looks set to be kept out of the firing line until their investigation is completed . That could be as early as Wednesday , as the English game 's governing body strives to prevent the issue dragging on as other racism cases that have dogged soccer of late . Chelsea captain John Terry has only recently completed a four match ban for using racist language during a Premier League game with Queens Park Rangers in October 2011 . The FA could only reach their own verdict after Terry 's case had been heard in a criminal court and in July the former England captain was found not guilty of racially abusing Anton Ferdinand , brother of Manchester United defender Rio . Chelsea chairman Bruce Buck rejected criticism of the club on Tuesday after they were labeled hypocritical for their handling of the Clattenburg and Terry situations . He told the London Evening Standard newspaper : `` Suppose we had tried to sweep this under the rug and said to the various players , 'Look , it 's not a big deal and the press are going to be all over us , maybe you want to reconsider . ' `` If that had leaked out , we would 've really been crucified . The press seem to juxtapose 'our support ' of John Terry and what 's going on here and looking at us as being a bit hypocritical . We have to divorce the John Terry situation from this . '' Last season Liverpool striker Luis Suarez was banned for eight matches after being found guilty of racially abusing Manchester United 's French defender Patrice Evra . Recently , a number of black players refused to wear T-shirts promoting an anti-racism campaign in protest at a perceived lack of action about the problem .
