You might well recognise the man who invaded the Eurovision stage
He has form with this kind of thing.
Another year, another Eurovision. Ireland finished respectably in 16th place - though our neighbours in the UK could only manage 24th.
To be fair, however, SuRie had an excuse: her song was interrupted by a protestor.
After storming the stage and grabbing the mic, the man appeared to shout: "For the Nazis of the UK media we demand freedom". He was quickly ushered offstage by security and SuRie managed to complete her performance.
Relive the #drama:
And it now seems that the stage-invader has done this kind of thing before: he stormed the stage last year during the final of The Voice final last year and tried the same thing at the National Television Awards. He goes by the name Dr ACactivism online.
He was taken into police custody following the disruption. The European Broadcasting Union issued a statement following the incident.
"The EBU regrets a stage invasion took place during the UK performance. The person responsible is currently in police custody," it read.
"The UK singer SuRie and her team were offered the option to sing again but decided not to because they were extremely proud of her performance and have decided that there is absolutely no reason to perform the song again."

At the NTAs Dermot O'Leary was forced to confront him and see him off stage.
Well done, Dermo!
