An Olympics official has been expelled from the ongoing Olympics after he was spotted making a shocking hand gesture.

The man was caught on camera doing the controversial signal during the women’s street skate finals on Sunday with some claiming the gesture is linked to a disturbing far-right movement.

The man was seen appearing to make an ‘okay’ hand sign with his thumb and index finger creating a circle and his fingers outstretched.

He repeated the action twice with his hands down by his side.

First as Australian ace Chloe Covell was competing before repeating it behind the Japanese athlete Liz Akama. It is unclear how he intended the symbol to come across. Traditionally, the "okay" gesture is used by a person to show they are fine and doing well.

In recent years it has become used far more frequently by far-right groups - sparking outrage over it being shown on the screens. The Anti-Defamation League (ADL) described the gesture as a “sincere expression of white supremacy". It has regularly been used by “right-leaning individuals" in pictures on social media, the ADL added.

A Brazilian journalist first reported the man - later identified as a subcontractor at the Olympics organizers before they reviewed the footage from the La Concorde Urban Park.

The man had positioned himself into a spot where he would be clearly seen on the huge broadcasting screens, the journalist claims.

The unnamed official was later identified as a subcontractor by the Olympic Broadcasting Services (OBS).

They announced he had his accreditation "cancelled effective immediately".
