(Reuters) - A Somali national has been convicted in an Ontario court for his role in the 2008 kidnapping of Canadian Amanda Lindhout, who was held captive in Somalia for 460 days and released only after her family paid a ransom, Canadian media reported on Wednesday. Ali Omar Ader, 40, was found guilty of one charge of hostage-taking for his role as negotiator for the kidnappers, in a decision handed down on Wednesday in Ontario Superior Court in Ottawa. Lindhout, a freelance journalist, was taken hostage in Somalia on Aug. 23, 2008, along with Australian photographer Nigel Brennan, while working on a story. They were released for ransom in November 2009.    Ader was lured to Canada from Somalia in 2015 and arrested in Ottawa as part of a sting operation by the Royal Canadian Mounted Police in which an officer posed as a publisher interested in a book Ader was writing on Somalia, according to court documents. Prosecutors argued that Ader had been the main spokesman for the hostage-takers, negotiating first with Lindhout s mother and later with a private consultant hired by the families of Lindhout and Brennan. According to court documents, he referred to himself as  a commander  and repeatedly threatened that the hostages would be harmed or killed unless the ransom was paid. During his trial, Ader said that he too had been kidnapped by the group holding Lindhout captive, and was forced to act as their spokesman, as he spoke some English.  In his ruling, Justice Robert Smith said Ader s claims were  completely unbelievable,  numerous Canadian media outlets reported. Reuters has not read the ruling. Ader faces up to life in prison. Sentencing in the case is not expected until next year. Lindhout has said she was repeatedly sexually and physically assaulted during her captivity, and both she and Brennan have said they were tortured and starved.  In 2013, Lindhout recounted her experience in the book  A House in the Sky.
