Hong Kong’s Chief Executive Leung Chun-ying said on Monday he would take up the alleged kidnapping cases of Causeway Bay booksellers with the central government.
He said he would write to Beijing expressing the growing concerns of Hongkongers especially after bookseller Lam Wing-kee, in an explosive interview last week, claimed he was kidnapped and kept in illegal detention, Radio Television Hong Kong reported.
Hong Kong may send officials to the mainland to pursue the matter if necessary, he said.
A memorandum detailing the norms to be followed by mainland authorities over arrests of Hongkongers on the mainland may also be reviewed.
Lam said Sunday he was so depressed during his detention that he considered suicide.
He told The Associated Press that he thought about using his clothes to hang himself but could not find a way to do it in the small room where he was kept under constant watch for five months.
Lam and four other men who worked for a Hong Kong publishing company disappeared last year, only to turn up months later in police custody on the mainland.
The publisher specialized in gossipy books on China’s communist leadership that were popular with Chinese visitors to Hong Kong but banned on the mainland.
