The court said Monday it had issued a public notice for the 31-year-old to appear in court but he failed to show up. Hailemedhin is in Switzerland, his brother Endalamaw Abera said.
At the time of the hijacking, Hailemedhin's uncle Alemu Asmamaw told The Associated Press in a telephone interview that the pilot was in emotional distress following the sudden death of another uncle.
On February 14 last year Hailemedhin, who had worked for Ethiopian Airlines for five years, locked the pilot of a Rome-bound flight out of the cockpit and then as co-pilot diverted the plane to Geneva, where he used a rope to lower himself out of a window and then asked for political asylum.
