Novak Djokovic back in detention as Australia cancels visa

Novak Djokovic was again detained in Australia Novak Djokovic was again detained in Australia Saturday, after authorities ripped up his visa for a second time and declared the unvaccinated tennis superstar a threat to the public.

Court documents showed the 34-year-old Serbian was currently being detained at an address in Melbourne, as his appeal against deportation is heard. Just two days before the Australian Open begins, the world number one is again focused on law courts rather than centre court in the latest twist in a high-profile row over his Covid-19 vaccine status.

Immigration minister Alex Hawke now claims Djokovic's continued presence in the country could "foster anti-vaccination sentiment" and even spark an "increase in civil unrest".Djokovic was summoned to appear before immigration officials in Melbourne ahead of emergency Federal Court hearings on Saturday and Sunday.

He was allowed to follow court proceedings from an address -- believed to be his lawyers' offices -- under guard of two Australian Border Force officers.This is the second attempt by Australia's conservative government to deport Djokovic, one of the world's most high-profile Covid-19 vaccine sceptics.
