Violence broke out in Melbourne earlier on Monday following Novak Djokovic's court case against the Australian government. The city's police force subsequently tried escorting the Serb out of the area in a black car but was met with a crowd of protesters, many of whom were possibly Djokovic fans.Djokovic's visa was revoked by the federal government last week after the Australian Border Forces didn't allow the World No. 1 entry into the country. The Serb challenged the decision in court and came out on top earlier on Monday.Djokovic reportedly bided his time in his lawyers' office as the Minister of Immigration Alex Hawke presided over whether the World No. 1's visa should be canceled. According to a report by an Australian tabloid, Hawke took nearly four hours to evaluate what needed to be done, ultimately deciding not to exercise his powers amidst public unrest.The Age@theageUpdated:Novak Djokovic is free to leave his lawyer's CBD office after Immigration Minister Alex Hawke declined to make use of a four-hour window to cancel the tennis star's visa under the Migration Act | #Kyrgios #COVID #AustralianOpen theage.com.au/sport/tennis/n…3:48 AM · Jan 10, 202218381Updated:Novak Djokovic is free to leave his lawyer's CBD office after Immigration Minister Alex Hawke declined to make use of a four-hour window to cancel the tennis star's visa under the Migration Act | #Kyrgios #COVID #AustralianOpen theage.com.au/sport/tennis/n… https://t.co/VwhypKaPA8Djokovic proceeded to leave his lawyers' office in a black car escorted by the Melbourne police force, according to reports. The Serb, however, was tracked down by a crowd of fans and protesters on the street adjacent to his lawyers' office and things soon got out of hand as the crowd started gathering around the Serb's car.Although a large majority of Djokovic's supporters did not indulge in violence, with many of them resorting to "Free Nole" chants, there were a few fans who probably got too close.Paul Sakkal@paulsakkalSerbian fans arriving at the Melbourne building that Djokovic is in with his lawyerLots of folk music, group dancing and "free Nole" chantsAnd a few shouts of "sack Dan Andrews" because we're still in Melbourne after all @theage2:54 AM · Jan 10, 2022634152Serbian fans arriving at the Melbourne building that Djokovic is in with his lawyerLots of folk music, group dancing and "free Nole" chantsAnd a few shouts of "sack Dan Andrews" because we're still in Melbourne after all @theage https://t.co/NZjq2TgRl9Police began pepper-spraying bystanders as soon as they sensed danger, causing violence to break out on Collins Street.As police dealt with protesters who swamped Djokovic's car, several glass bottles and other items were hurled at the Serb's entourage.
