Former Russian army officer Bout, 42, remains in custody in a Thai jail after the Bangkok Criminal Court refused in August to extradite him to the United States, where he is facing four terrorism-related charges and a possible life sentence.

“I was informed that my client had been asked to appear in court on February 16. However, I was not told why he had been summoned,” Thai lawyer Chamroen Panompakakom told RIA Novosti.
