NICOSIA, Cyprus (AP) — An Egyptian man who hijacked a domestic EgyptAir flight in 2016 and ordered it to land in Cyprus has been extradited to his homeland after giving up a drawn-out legal fight, authorities said Sunday.

Seif Eddin Mustafa was transferred to Egyptian custody and flown back to Egypt late Saturday, where prosecutors are investigating the incident. Cyprus Justice Minister Ionas Nicolaou told The Associated Press that Mustafa’s extradition went ahead after he dropped a three-year court battle to avoid extradition.

Mustafa had challenged extradition on the grounds that he could face torture or an unfair trial in Egypt.

Mustafa hijacked the EgyptAir flight in March 2016 using a fake suicide belt and diverted it to the Mediterranean island of Cyprus. A six-hour standoff with Cypriot authorities on the tarmac of Cyprus’ Larnaca airport ended peacefully after all 72 passengers and crew were released and Mustafa was arrested.

Mustafa told a Cypriot court that he meant no harm to anyone. He said he was trying to expose what he called the “fascist regime” of Egyptian President Abdel-Fattah el-Sissi and to help secure the release of 63 female dissidents being held in Egyptian prisons.

But prosecutors said Mustafa admitted in a written statement to police that he only carried out the hijacking in order to reunite with his Cypriot family, from whom he had been estranged for 24 years. Mustafa dismissed the written statement as “purposeful misinformation” by the Cypriot and Egyptian governments put out to discredit him.

Doros Polycarpou, with the migrant support group KISA that assisted Mustafa, told the AP that the 62-year-old decided of his own accord to return to Egypt and face prosecution there, despite fears that he may be tortured. Egypt and Cyprus have a 1996 extradition treaty.

Polycarpou said Mustafa told his legal team he was willing “to take the risk” of suffering mistreatment at the hands of Egyptian authorities because he could “no longer take” his holding conditions in Cyprus’ prison complex.

He said Mustafa had complained that he was being held in “isolation” and put under “psychological strain” because authorities kept him away from the prison’s general population.

Last year, the European Court of Human Rights blocked Cyprus from extraditing Mustafa until it could rule on whether doing so would violate its prohibition on returning individuals to countries where they may face torture or inhuman treatment.
