Rapper Wiley, known as the “godfather of grime”, has been dropped by his management following anti-Semitic posts on his social media accounts.
Wiley suggested Twitter had temporarily banned him from tweeting after a long series of posts on Friday and Saturday, but he remains active on Instagram.
The social media giants are facing growing pressure to close his accounts.
Police said they were looking at “relevant material” as critics accused Wiley of incitement to racial hatred.
Metropolitan Police officers in Tower Hamlets said in a statement: “We have received a number of reports relating to alleged anti-Semitic tweets posted on social media. The Met takes all reports of anti-Semitism extremely seriously. The relevant material is being assessed.”
There are also calls for Wiley’s MBE, appointed for services to music, to be revoked.
Wiley, 41, shared conspiracy theories and insulted Jewish people on his Instagram and Twitter accounts, which together have more than 940,000 followers.
In one tweet he said: “I don’t care about Hitler, I care about black people”, and also compared the Jewish community to the Ku Klux Klan.
On Instagram, videos of himself were interspersed with posts of screenshots – which have since been deleted – including one at about midday on Saturday suggesting Twitter has suspended him from tweeting for a week.
He had already been given a 12-hour ban on Friday night, but resumed tweeting on Saturday.
The platform has removed some of his tweets, with a note saying they violated its rules.
Wiley’s manager, John Woolf, confirmed that the Twitter account, which is not verified, belongs to the London-born rapper, whose real name is Richard Cowie.
