Novak Djokovic’s father, Srdjan, appeared to be among those posing for photos with pro-Vladimir Putin flags at the Australian Open on Wednesday.

Srdjan Djokovic was seen outside Rod Laver Arena standing next to a man wearing the pro-Russian «Z» on his jersey and holding a Russian flag with Putin’s face plastered on it.

According to The Guardian, a video posted on YouTube appeared to show Djokovic saying «long live Russian citizens» in their language.

The photo of the tennis great’s father and Russia supporter came after Australian Open officials expelled several people from the tournament for their behavior.

Tennis Australia released a statement saying police intervention was needed during the incident.

«Four people in the crowd leaving the stadium revealed inappropriate flags and symbols and threatened security guards,» the statement said, via BBC. «Victoria Police intervened and continue to question them. Everyone’s comfort and safety is our priority and we work closely with security and authorities.»

The Russian and Belarusian flags have been banned from the tournament, although it was initially allowed if no disruption occurred. That was reversed last week after a women’s match between Ukraine’s Kateryna Baindl and Russia’s Kamilla Rakhimova, when a Russian fan displayed a flag during the match.

The Australian Open has also been using a neutral flag for all Russian and Belarusian players due to the current invasion.

Since the invasion of Ukraine began last February, Russian and Belarusian athletes have not been able to play under their own flags.
