[1] In 2000, and again following the September 11, 2001 attacks, CSIS agent Violaine Pepin spoke to him to ask about a Muslim associate with a pilot's license with whom Almalki had flown to Hong Kong in 1999 to sell radios in the final weeks of Y2K.

They met at the Mango Café, a popular shawarma restaurant in a strip mall and talked about doctors and bought a print cartridge together.

[7] Almalki was released on $125 bail in March 2004 and the Syrian State Supreme Security Court acquitted him of all charges in July 2004.

According to historian Andy Worthington, author of The Guantanamo Files, Almalki described three of his fellow captives in Syria's Palestinian Branch military prison: Omar Ghramesh, Abu Abdul Halim Dalak and a Syrian teenager who was captured during the same raid where Abu Zubaydah was captured, who Worthington concluded was Noor al-Deen.
