The Premier League referee was accused of using racist comments toward Chelsea midfielder John Obi Mikel, but police have ended the investigation into the matter.
The official had come under scrutiny after Chelsea duo John Obi Mikel and Juan Mata both raised complaints following the Blues 3-2 Premier League defeat to Manchester United last month; however, police have since stated that "without a victim and/or any evidence that any offense has been committed," there is no line inquiry that can be pursued.
"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," the police said in a statement. "This follows on from a complaint received by the Metropolitan Police Service on 29 October. Enquiries were made and no victims have come forward. 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."
Chelsea quickly dropped the Mata's allegation against the 37-year-old, although the Blues have continued to support the Nigerian midfielder, with club chairman Bruce Buck once again discussing the complaint on Tuesday.
“The reaction has been very unfair,” Buck told the Evening Standard. “We weren’t interested in any confrontation with the referee or anybody else, had no thoughts of revenge on the referee. 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.
“I spoke to the players involved, either because they were allegedly the recipient of that abuse or had heard it, three separate times. I asked them if they could be mistaken. I asked them, if they might have heard 'Mikel' instead of 'monkey'. I thought I had covered that base.
“[The decision] was made after a great deal of anguish and after talking long and hard that evening about what should we do.”
