A protester grabs SuRie's microphone during her act, leaving the artist visibly shaken, but SuRie manages to complete her performance.

The European Broadcasting Union said: "The person responsible is currently in police custody."

SuRie declined to perform again, saying there was "absolutely no reason to" because they were "extremely proud of her performance".
