The wife of one of five missing Hong Kong booksellers said she met with her husband in China, according to a statement released by the Hong Kong police on Sunday amid growing diplomatic pressure on Chinese authorities to clarify the fate of the men.
Lee Bo, 65, an owner of a publisher and bookshop specializing in books critical of China's Communist Party leaders, vanished in late December amid widespread speculation that Chinese authorities may have abducted him in the financial hub and spirited him across to China for an investigation.
Lee, who has dual Hong Kong and British citizenship, surfaced on Saturday, meeting his wife at a guesthouse in mainland China, the Hong Kong police said in a statement issued after midnight on Sunday.
His wife, Sophie Choi, told police that she had met with her husband at a guesthouse in China on Saturday and that he was healthy and in good spirits.
The statement cited Lee's wife as saying he was "assisting in an investigation in the capacity of a witness," though she didn't give specifics on the location nor the nature of the investigation, the statement added.
The Hong Kong police said they would continue to probe the case, and would put in a fresh request with police in China's southern Guangdong province to arrange a meeting with Lee Bo.
Calls to the mobile phones of Lee and his wife went unanswered.
