Supporters of mainland dissident Liu Xiaobo said on Wednesday they were still unable to get in touch with his wife, Liu Xia, as they marked the the seventh day after the death of the Nobel Peace Prize winner.
The Hong Kong-based Information Centre for Human Rights and Democracy quoted one of Liu Xia's relatives as saying she had been taken by mainland authorities to Yunnan province "for a holiday".
Security has also been beefed up outside her apartment in Beijing, with authorities standing guard and questioning reporters who tried to pay a visit.
Her friend, author Ye Du, also claimed on social media that he has been taken away by the police "for a vacation" somewhere away from the river and the sea.
Meanwhile, a supporters' group was planning a global memorial on social media on Wednesday in honour of the late Nobel laureate.
In Hong Kong, the Alliance in Support of Patriotic Democratic Movements in China said they would also hold a candlelight vigil at Tamar Park to mark the occasion.
Liu Xiaobo died at the age of 61 last Thursday of liver cancer. He was detained in 2008 after publishing a document that called for democracy and human rights in China. He was sentenced in 2009 to 11 years in prison for "subversion".
