Given the Chinese government's propensity for secrecy, there probably won't be any solid news until the matter is sorted out behind closed doors, and Fan pays up for her rumored tax transgressions and makes a contrite statement to the public. Then came the celebrity-ranking report in which Fan ranked last, with just nine of the 100 celebrities reviewed on their work, philanthropy, and personal integrity deemed to be "socially responsible".
Fan's name was brought into a tax evasion scandal in China after a TV host leaked documents that showed an unnamed movie star, who was identified online as Fan, was involved in an alleged tax-dodge scheme.
Fan is one of five leading worldwide actresses cast in the upcoming Hollywood spy thriller 355, also starring Jessica Chastain and Penelope Cruz.
Last week, China's state-run Securities Daily said that Fan was "under control, and will accept the legal decision", several news outlets, including Taiwan News, reported.
Other news outlets have for months speculated on Fan's whereabouts, and rumors circulated that she was living under house arrest, according to The Epoch Times, a United States newspaper focusing on China.
So-called "yin and yang" dual contract arrangements ― with one contract for income declared to tax authorities and another kept secret ― are reportedly used to evade taxes.
Defiant Australian paper reprints ‘racist’ Serena cartoon
Every time we cry foul over tennis goddess Serena Williams being victimised in a "white man's game", we fail as Serena fans. The cartoon was intended as a lampoon of the tennis star's angry exchanges with chair umpire Carlos Ramos at the U.S.
The actress's troubles began when Cui Yongyuan, a former presenter for state-run China Central Television (CCTV), posted purported contracts online in May that suggested she had received under-the-table payments.
But shortly after it was published, that report appeared to have been taken offline.
In late July, the independent Chinese newspaper The Economic Observer reported that police in Jiangsu province were examining Fan's financial case and that several of Fan's staff members were also under police investigation.
Last year, she topped Forbes magazine's list of top-earning Chinese celebrities with income of 300 million yuan (£33.5m).
The 2017-2018 China Film and Television Star Social Responsibility Report ranked stars based on three main criteria - their film and television work, their charitable activities and their behaviour.
Posts about Fan's whereabouts earlier this year were also removed from social media, according to Free Weibo, a website that tracks social-media censorship in China. It found that Fan scored zero out of 100 points.
Her studio denied any wrongdoing from her side.
