Police who were investigating Kneecap’s performance at Glastonbury will not take any further action.

Last month, a criminal investigation was launched by Avon and Somerset Police into performances by the Irish language rap trio at the music festival.

It said it had appointed a senior detective to investigate whether comments made on stage amounted to a criminal offence after reviewing footage.

On Friday, the force said detectives had sought advice from the Crown Prosecution Service and chosen not to take any further action against Kneecap on the grounds that there was “insufficient evidence to provide a realistic prospect of conviction for any offence”.

“Kneecap was informed of that decision earlier today (Friday 18 July),” it added.

“Enquiries continue to be carried out in relation to separate comments made on stage during Bob Vylan’s performance.”

The force have also been investigating English punk-rap duo Bob Vylan’s performance.
