Authorities in Britain will attempt to return the brother of the Manchester Arena suicide bomber back from Libya.
Anti-terror police have lodged an extradition request for Hashem Abedi, who is custody in the north African country.
Both he and his brother Salman travelled to the country in April, before the latter returned to the United Kingdom alone.
He subsequently carried out the attack in May which left 22 dead and hundreds injured, detonating a home-made explosive in crowds leaving Manchester Arena after a concert by US singer Ariana Grande.
The police authorities have previously said they don’t believe Abedi had been part of a larger terrorist network, but do think others – with Hashem a suspect - played a hand in planning the attack in Manchester.
The UK and Libya had agreed an extradition arrangement in 2009 but the overthrow of Gaddafi has seen the country divided into warring factions.
