POLICE have launched a criminal probe into an alleged torrent of anti-Semitic hate from Labour members, Scotland Yard announced today.

Met officers are examining an internal Labour dossier after it was handed to the force's boss earlier this year.

They are now considering whether to bring criminal charges against the activists who've been accused of racism.

The dossier, apparently compiled by Labour officials, detailed 45 claims of anti-Semitic behaviour and was published by LBC in September.

The file included messages such as “We shall rid the Jews who are cancer on us all”.

Among the vile slurs allegedly spread by Labour activists were "these Jewish f**kers are the devils" and calling supporters of Israel "Anglo-Zio-Nazis".

One party member subjected a young boy to "ten years of hell" by repeatedly calling him racial slurs such as "Jew-boy", according to the dossier.

When the allegations came to light, Met Police commissioner Cressida Dick vowed to look into them.

Today Scotland Yard officials confirmed they have opened a formal investigation.

A spokesman said: "On Tuesday September 4, the Met Commissioner was handed a folder of paperwork following a radio interview with LBC Radio in Leicester Square.

"The complainant alleged that the documentation included evidence of anti-Semitic hate crimes.

"The contents have been examined by specialist officers. A criminal investigation has commenced into some of the allegations within the documentation.

"Early investigative advice is being sought from the Crown Prosecution Service."

Ms Dick said that the party is not directly under investigation, but added: "If somebody passes us material which they say amounts to a crime we have a duty to look at that and not just dismiss it.

"We have been assessing some material that was passed to me... and we are now investigating some of that material because it appears there may have been crime committed.£

A Labour spokesman said today: “The Labour party has a robust system for investigating complaints of alleged breaches of Labour party rules by its members.

"Where someone feels they have been a victim of crime, they should report it to the police in the usual way."

Amanda Bowman of the Board of Deputies of British Jews blasted: "This comes as no surprise to us.

"There is a deeply embedded culture of anti-Semitism in parts of the Labour party and Jeremy Corbyn has done close to nothing to address it, to the extent that some cases may now even meet a criminal threshold."

It is understood Scotland Yard has not directly contacted the party to discuss the case, but Labour bosses are prepared to help with the investigation if asked.

Deputy leader Tom Watson said news of the police probe was "thoroughly depressing", but added: "Sadly, I'm not surprised."

Labour has been struggling to deal with anti-Semitic abuse from far-left activists ever since Jeremy Corbyn became leader three years ago.

The party boss has been accused of not doing enough to tackle racist hatred from members.

Mr Corbyn today refused to answer questions from reporters about the police investigation.
