During Bob Vylan’s set, the band’s singer Bobby Vylan (born Pascal Robinson-Foster) led Glastonbury crowds in chants of both “free, free Palestine” and, more controversially, “death, death to the IDF.”

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 said Monday it should have pulled a livestream of rap duo Bob Vylan’s performance at the Glastonbury Festival, which saw the group leading crowds of music fans in chants calling for “death” to the Israeli military.
