Bob Vylan's US visas has been revoked following their highly controversial performance at Glastonbury. The music duo, who go by stage names Bobby Vylan and Bobbie Vylan, sparked outrage when singer Bobby-whose real name is Pascal Robinson-Foster-called for "death to the IDF [Isreal Defence Force]" during their performance at Worthy Farm. Avon and Somerset Police are investigating the pair's performance, as well as that of Irish rap trio Kneecap.

After rumours swirled on Monday that the men behind Bob Vylan would be barred from the US, the Deputy Secretary of State Christopher Landau wrote on X: "The (State Department) has revoked the US visas for the members of the Bob Vylan band in light of their hateful tirade at Glastonbury, including leading the crowd in death chants. Foreigners who glorify violence and hatred are not welcome visitors to our country."

In the wake of the Ipswich double act's performance, the US ambassador to the UK, Warren Stephens, said: "The antisemitic chants led by Bob Vylan at Glastonbury were a disgrace.

"There should be no place for this hateful incitement or tolerance of antisemitism in the UK."

The group has 26 concerts scheduled as part of their upcoming US tour, lasting between late October and mid-December this year. However, it is unlikely the tour can go ahead without the performers possessing visas.

Avon and Somerset Police has said it is investigating the remarks made during Bobby Vylan's show, as well as those made on-stage by members of Kneecap. Sir Keir Starmer said earlier this year that it would "inappropriate" for Kneecap to play at Glastonbury after video footage surfaced of band member Liam Og O hAnnaidh saying "up Hamas, up Hezbollah" during a performance.

Referencing the call from the PM to axe Kneecap's show, Naoise O Caireallain, also in the band, said during their Glastonbury set: "The prime minister of your country, not mine, said he didn't want us to play, so f*** Keir Starmer." The trio then led the crowd in chants of "f*** Keir Starmer" and "Free Palestine".

Avon and Somerset Police said: "Video footage and audio from Bob Vylan and Kneecap's performances at Glastonbury Festival on Saturday has been reviewed.

"Following the completion of that assessment process we have decided further inquiries are required and a criminal investigation is now being undertaken. A senior detective has been appointed to lead this investigation.

"This has been recorded as a public order incident at this time while our inquiries are at an early stage. The investigation will be evidence-led and will closely consider all appropriate legislation, including relating to hate crimes.

"We have received a large amount of contact in relation to these events from people across the world and recognise the strength of public feeling. There is absolutely no place in society for hate.

"Neighbourhood policing teams are speaking with people in their local communities and key stakeholders to make sure anyone who needs us knows that we are here for them. We hope the work we have carried out, and are continuing to carry out, reassures the public how seriously we are treating Saturday's events.

"We politely ask the public refrain from continuing to report this matter to us because an investigation is already taking place."
