THE Netherlands’ Eurovision entry has been banned from rehearsing until “further notice” after an unexplained “incident”.

Joost Klein, 26, is under investigation from the European Broadcasting Union following the “incident”.

He is known to have missed the penultimate dress rehearsal in Malmo, Sweden on Friday.

Klein is due to perform immediately before Israel’s entry Eden Golan during the grand final on Saturday.

However, it is unclear whether he will be permitted to go ahead with his scheduled performance.

The EBU said in a statement: "We are currently investigating an incident that was reported to us involving the Dutch artist. He will not be rehearsing until further notice.

"We have no further comment at this time and will update in due course."

It comes after Klein interjected during a question put to Golan at a press conference on Thursday evening.

After a Polish news outlet asked Golan is she thought her presence was causing a security risk for other performers, Swedish presenter Jovan Radomir said that she did not have to answer the question if she did not wish to.

Klein then shouted: “Why not?”

It comes as tensions rise ahead of the final, which is set to be subject to large boycott due to the EBU’s decision to allow Israel to compete.

Golan was booed by crowds following her semi-final performance.
