Police in London have dropped their investigation into the Premier League referee who was accused of racially abusing Chelsea midfielder John Obi Mikel.
Mark Clattenburg was accused of insulting the Nigerian midfieleder during the European champions' 3-2 loss to Manchester United at Stamford Bridge last month.
The complaint came from the Society of Black Lawyers after Chelsea players said Mikel had been abused.
A Metropolitan Police statement said the case had been dropped because no victims had come forward.
"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 cannot 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."
The Football Association is also looking into whether the 37-year-old official made "inappropriate" comments towards Mikel following a complaint from Chelsea.
Chelsea chairman Bruce buck defended their decision to go public with the complaint.
"It was made after a great deal of anguish and after talking long and hard that evening about what we should do," Buck told the Daily Mail.
"We were guided by obligations that are imposed by the Football Association and also as an employer. FA rule E14 basically says a participant shall immediately report to the association any incident or matter which may be considered to be a misconduct.
"Misconduct is a defined term under the FA regulations and includes such racial behaviour. We also had to consider the Equality Act 2010, which imposes an obligation on an employer to take certain actions if an employee is subject to discrimination by third parties.
"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."
Clattenburg has not taken charge of a game since the heated October 28 clash.
