An ambulance believed to be carrying suspected Nazi death camp guard John Demjanjuk has left U.S. immigration offices in Cleveland as federal agents prepare to deport him to Germany.

Immigration officials would not comment Monday evening on where the ambulance was headed, but it drove toward nearby Cleveland Burke Lakefront Airport, located several blocks away.

Demjanjuk was taken by ambulance from his Ohio home late Monday afternoon to the customs office in Cleveland and is expected to be deported to Germany by Tuesday.

The retired 89-year-old autoworker is wanted on a Munich arrest warrant that accuses him of 29,000 counts of accessory to murder while allegedly working as a guard at the Sobibor death camp in Nazi-occupied Poland.

Demjanjuk remained inside his suburban Cleveland home Monday until 3 p.m. when he was escorted out through his garage and immediately into the ambulance.

Chronology of the John Demjanjuk Case

His daughter Irene and her two children arrived at his home Monday morning. His other daughter Lydia arrived later with her husband, WOIO reported. Shortly after two priests arrived followed by his son John.

U.S. Immigration and Customs Enforcement officials went to Demjanjuk's home Friday to serve a government notice asking that he surrender. The move came one day after the U.S. Supreme Court declined to hear Demjanjuk's appeal to stop his deportation.

Demjanjuk rejects the German allegations. He maintains he was held by the Germans as a Soviet prisoner of war and was never a camp guard.

Once in Germany, Demjanjuk will be brought before a judge and formally charged. He will also be given the opportunity to make a statement to the court, in keeping with normal justice procedure, German Justice Ministry spokesman Ulrich Staudigl said.

Demjanjuk's family has been battling the deportation, saying he is in poor health and might not survive the trans-Atlantic journey.

Once in Germany, Demjanjuk is expected to be held in the medical unit of a Munich prison. The government has said preparations have been made at the facility to ensure he will receive appropriate care.
