Q: Last weekend  around 10 plain-clothes police officers escorted Gui Minhai from a train traveling from Chinaâs eastern coastal city of Ningbo to Beijing  his daughter Angela Gui told Hong Kongâs South China Morning Post Monday.
Gui Minhaiâ a naturalized Swedish citizen â was traveling with two Swedish diplomats when he was detained  his daughter said.
In a statement issued to multiple outlets  Swedenâs foreign minister Margot WallstrÃ¶m said that her government had âdetailed knowledgeâ of Gui Minhai âs arrest and had summoned Chinaâs ambassador.
 The 2015 disappearance of Gui Minhai and four other Hong Kong-based publishers and booksellers â who sold books banned on the mainland â provoked consternation in the semi-autonomous territory  where many regarded it as an incursion into Hong Kongâs sovereignty . The five later appeared in Chinese custody and gave statements saying  they  had gone to the mainland voluntarily.
Angela Gui told the New York Times that her father  who China formally released from detention last October  had been living in Nigbo and was required to report regularly to Chinese authorities.  Gui Minhai  was reportedly en route to Beijingâs Swedish Embassy for a medical examination when police boarded the train and ushered him away.
