Haile Satayin's Olympic preparations took an unexpected twist for the worse after he was arrested upon his arrival at Addis Ababa Airport in Ethiopia. The 53-year-old runner, who will compete in the Olympic marathon on August 24, spent four days under arrest in January in Ethiopia after an acquaintance claimed he had stolen money from him. It's still unclear whether his current arrest is also connected with that case. "The state of Israel and the Israeli Athletics Association are doing all they can to bring [about] Satayin's quick release," IAA chairman Shlomo Ben-Gal said on Wednesday and promised no effort will be spared to help the veteran runner. In other Olympic news, the Israeli fencer, 27-year-old Delila Hatuel - whose participation in the Beijing Olympics was in doubt after a knee injury - is recuperating after undergoing treatment in the hyperbaric oxygen chamber at Assaf Harofeh Medical Center in Tzrifin. The edema (swelling) in her knee disappeared, said Dr. Shai Efrati, the chamber director. "She will need seven more treatments before she flies to China." Judy Siegel contributed to this report.
