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.

The BBC struggled through its latest efforts to deal with Irish hip hop group Kneecap today, choosing not to stream the group’s massively attended set at the Glastonbury Festival this weekend under worries that the band would offer up incendiary messages condemning both the British government and the Israeli occupation of the West Bank.

The BBC has revealed how it plans to show Kneecap ’s Glastonbury performance later today. The corporation has confirmed that the performance will not be streamed live but will be shown on-demand.
