Missing Leeds girl Elsa Salama's mother suffering agony that is hard to imagine, says High Court judge

Former teacher Tamer Salama took four-year-old Elsa Salama from her mother Naomi Button in December 2011 while all three were visiting his relatives in Egypt.

Ms Button, a leadership consultant from Leeds, was forced to return to England alone and has not seen Elsa, now 12 and thought to be living with Salama's mother in Cairo, since.

She launched family court litigation after arriving back in the hope of getting Elsa home and is continuing that fight.

But a judge ordered his release in December 2013 after deciding that continuing to keep him in prison was no longer proportionate or justifiable.

Mr Justice Mostyn, who is overseeing the latest stage of litigation, said on Tuesday that Ms Button and Elsa were victims of "formidable" cruelty.

He said, in a ruling published following a hearing in the Family Division of the High Court earlier this month, that Salama had allowed Ms Button a "few occasions of Skype contact" which ceased more than two years ago.

"It is hard to imagine the daily agony that this mother must endure."

Salama says he does not know where Elsa is.

He added: "I am convinced that Elsa's continued abduction is done with the active complicity of the father and at his behest."

Mr Justice Mostyn had said at the hearing earlier this month that he would ask Foreign Secretary Jeremy Hunt for help finding Elsa.

He formally made that request in his ruling on Tuesday and asked Mr Hunt to use all "diplomatic measures" to trace the youngster.
