Novak Djokovic isn’t alone in having his visa canceled after flying in for the Australian Open without the required evidence to support a medical exemption to the country’s strict COVID-19 vaccination rules.

Djokovic was denied entry when he arrived at Melbourne’s airport on Wednesday and was still in an immigration detention hotel on Friday, awaiting a court hearing to challenge his deportation, when the Australian Border Force confirmed that action was taken against two other people.

In an e-mail to The Associated Press, the border force said following investigations into two other cases of people connected to the Australian Open “one individual has voluntarily departed Australia … and the visa of a third individual has been canceled.”

The ABF said one person was taken into immigration detention pending deportation, but declined to to give details or make further comment.
