Members of the British rap punk duo Bob Vylan had their visas revoked by the US and are under investigation by local police after leading a crowd to chant “death” to Israel’s military at a UK music festival this past weekend.

British police have launched a criminal investigation into a performance by rap-punk duo Bob Vylan at the Glastonbury Festival on Saturday, when the group led chants of “death to the IDF,” or Israel Defense Forces.

Punk duo Bob Vylan have been dropped from multiple upcoming festivals in both the UK and abroad following their controversial performance at Glastonbury. The group had been due to headline Radar Festival in Manchester this Saturday, but organisers confirmed the band would no longer perform. The set was scheduled to take place at Victoria Warehouse.
