A prominent Austrian far-Right leader barred from entering the UK last year is facing investigation over suspected links with the gunman held for the New Zealand mosque attack.

The Austrian government announced on Wednesday that it may ban the far-Right Identitarian movement if any link is proved.

Martin Sellner, one of the movement’s founders and best-known figures, denied any involvement in the attack after his Vienna home was raided by police investigating the suspected links on Monday.

Prosecutors said the investigation had been triggered by a suspicious €1,500 (£1,270) donation to the movement.

They are believed to be investigating the possibility the donation was made by Brenton Tarrant, the main suspect in the terror attacks on two Christchurch mosques in which 50 people were killed.

“I have nothing to do with this terror attack,” Mr Sellner said in a video released on social media.

He admitted he had received an email and a “disproportionately large” donation from some one named Tarrant. He said he sent a reply to thank the donor, but claimed there was no other communication between them.
