Norfolk Constabulary had launched the probe after pupils from the Jewish Free School (JFS), in London, said they had been targeted during a match at Thorpe St Andrew School earlier this month.

The children claimed they had been told to “go back to the gas chambers” and called “dirty Zionists” by the crowd, which was mostly made up of pupils from Thorpe.

One mixed-race JFS pupil alleged he was called a "N***** Jew" during the game, the quarter final of national under-15 tournament organised by the English Schools' Football Association.

Another player also claimed he was called a "monkey" - a term that has been used by Islamic extremists as a slur against Jewish people.

However, following a review of footage from the match and interviews with those present - including officials and coaches and supporters of both teams - police said they found nothing to substantiate the claims.

A spokeswoman said: “Police have extensively reviewed footage of the football match, and taken multiple witness statements from those present at the time including match officials, team coaches and home and visiting supporters.

“Officers haven’t found any evidence that there was antisemitic chanting or language used at any time. Accordingly, without any evidence or independent verification of the allegation, it does not meet the evidential standards required to pursue criminal proceedings.”

The force has now closed the investigation and no further action will be taken.

The allegations sparked international coverage, with the New York Times and the Times of Israel among the publications to report on the claims.

Days later, the school found itself in the headlines again after a 15-year-old pupil was stabbed in the back with a carving knife. A 15-year-old boy has been charged with attempted murder.

Police have stressed that attack was not linked to the antisemitism allegations.

Following the closure of the investigation, a spokesman at Thorpe St Andrew School said: “The school and trust have cooperated fully and transparently throughout, providing all available evidence to support enquiries.

"We recognise that concerns were raised and have treated them with the utmost seriousness.

“Antisemitism and all forms of discrimination are completely unacceptable and have no place in our schools.

"We are delighted to announce that the U15 boys football team will be playing their ESFA National Cup semi-final fixture against Riddlesdown Collegiate after the Easter holidays."

JFS has been approached for comment.
