Kneecap's Liam O'Hanna has been charged with terrorism offences after he was accused of displaying a flag in support for Hezbollah at a London gig.
O'Hanna, 27, who performs under the stage name Mo Chara, is alleged to have displayed the flag showing the terrorist group while the controversial Irish hip-hop group performed at the O2 Forum in Kentish town last year.
The Met Police said the rapper, from Belfast, was showing the flag 'in such a way or in such circumstances as to arouse reasonable suspicion that he is a supporter of a proscribed organisation'.
The force's counter terror unit conducted an investigation into the event, on November 21, after they were shown a video in late April.
Hezbollah is a proscribed terror organisation, and it is a criminal offence under the Terrorism Act 2000 to 'invite support' for either group.
