A criminal investigation has been launched over performances by Bob Vylan and Kneecap at Glastonbury on Saturday, Avon and Somerset Police has said. The force said it had appointed a senior detective to investigate whether comments made by either act amounted to a criminal offence after reviewing footage.

UK police on Monday launched a criminal investigation into remarks made by rap groups Kneecap and Bob Vylan during the Glastonbury festival, as the US revoked visas for the latter after its frontman led an anti-Israel chant.

Kneecap’s performance at Glastonbury Festival will not be live-streamed but is likely to be made available on-demand, the BBC has said.A number of politicians have called for the Irish rap trio to be removed from the line-up and Prime Minister Sir Keir Starmer said their performance would not be “appropriate” after one of the members was charged with a terror offence.
