The family of a Montreal man stranded in Sudan for five years because he’s on a no-fly list will make a public plea to the Canadian government Tuesday to help bring him home.

“The family just wants to deliver a very clear message … to our prime minister and minister of foreign affairs, simply to bring [him] back. The children want their father back in Canada,” his lawyer, Yavar Hameed told CBC News. “He has a life here, he has connections here, and they want him back.”

Abousfian Abdelrazik, who was detained by Sudanese authorities while visiting his mother in 2003, has since been released from jail, but remains under police surveillance. Abdelrazik, who is a dual citizen of Canada and Sudan, hasn’t been charged with any crime in either country.

Hameed said his client has been deemed a security threat over Canadian Security Intelligence Service suspicions that he’s an al-Qaeda agent, something he denies. CSIS documents suggest it was CSIS agents who asked the Sudanese government to arrest Abdelrazik, Hameed said.

Ottawa has been putting up roadblocks to thwart Abdelrazik’s attempts to return to Canada, Hameed said, adding that Canada has ignored Sudan’s offers to facilitate Abdelrazik’s return to Canada.
