The police investigating the performance of Kneecap in Glestonbury will not take any further action.
Last month, a criminal investigation was launched by the Irish language rap trio at the concert by Avon and Summerset Police.
It said that it appointed a senior detective to check whether the comments made on the stage were a criminal offense after reviewing the footage.
On Friday, the force stated that the detectives had sought advice from the Crown Prosecution Service and on the basis that no further action against Neicap was chosen to “there were insufficient evidence to provide a realistic possibility of punishment for any crime”.
“Kneecap was informed about that decision earlier today (Friday 18 July),” it said.
“Inquiry is going on regarding the separate comments made on the stage during the performance of Bob Valn.”
The force is also investigating the performance of the English punk-rap pair Bob Valn.
