Eurovision Song Contest organisers have disqualified the Dutch entry from taking part in Saturday’s grand finale.
Joost Klein was sent home after allegations that he intimidated a female member of the song contest’s production crew, the European Broadcasting Union said.
The singer was originally among the favourites to win this year’s edition of the song contest, which is being held in the Swedish city Malmo.
"Swedish police have investigated a complaint made by a female member of the production crew after an incident following his performance in Thursday night's Semi Final," the European Broadcasting Union said in a statement.
"While the legal process takes its course, it would not be appropriate for him to continue in the Contest."
Swedish police told AFP they had questioned a man for alleged "intimidation".
"The offence was committed in the Malmo arena on Thursday evening," police spokesman Pelle Vamstad said.
Dutch public broadcaster Avrotros said it found the move "disproportionate", adding that it it was "shocked by the decision".
EBU shoots down rumours
The EBU dismissed rumours that Klein had clashed with another delegation or performer.
Klein was alleged to have had an altercation with Israel’s entry after he was not allowed to perform during a dress rehearsal on Friday evening. He covered his face with a flag while the Israeli Eden Golan answered questions at a press conference some days ago.
