The Campaign Against Antisemitism (CAA) are to launch a private prosecution against rapper Wiley the police said they would not pursue race-hate charges.

On Friday, the Metropolitan Police confirmed they would not bring a case against Wiley – whose real name is Richard Cowie – as he was abroad at the time of his offence.

In July, the grime artist posted a stream of antisemitic comments on Twitter and Facebook, including tropes about Jewish power and drawing comparisons between Jews and the KKK. In one post, he told the Jewish community to “hold some corn” – slang for being shot.

However, the JC previously understood that the rapper was in Rotterdam, Holland, when he posted the comments on Twitter and Facebook. Offences committed abroad must be brought to court in the country in which the crime was committed .

Stephen Silverman, Director of Investigations and Enforcement at CAA, said the Met police had closed the investigation due to “jurisdictional issues”, and that the organisation had “instructed lawyers abroad to pursue this matter.”

Mr Silverman added: “When antisemites incite hatred against Jews, we will pursue them, including across borders if necessary.”

CAA have also contacted the Cabinet Office about having the rapper stripped of his MBE, and have begun a petition to make this an automatic process for any racist with an honour. The charity also said it was “working with the music industry” to have Wiley stripped of his awards.
