He was released on Monday, however, after an Australian judge ruled that the cancellation of his visa was "unreasonable."
Shortly after he was released, however, journalist Ksenija Pavlovic McAteer tweeted to say that Djokovic's father, Srdjan, had told her that the 34-year-old had been arrested.
"We're currently consulting with PRs about next steps. He is at the moment with his lawyers in the room they were during the hearing, thinking about options."
According to Melbourne newspaper The Age, however, reports of Djokovic's arrest are inaccurate.

"Media reports from Europe quote Djokovic's family members alleging he has been re-arrested at his lawyers' office in Melbourne's CBD," wrote the outlet.
"However, the four sources including some from the federal government insist this isn't the case. There are no Border Force or federal police officers at the foot of the CBD tower Djokovic is located in."
Victoria Police did not immediately respond to Insider's request for comment late in the Australian evening Monday.
Despite Djokovic's visa having been reinstated on Monday, the threat of deportation is still looming over the 20-time Grand Slam champion.
