Hashem Abedi is believed to have known about his elder brother's plot to detonate the nail bomb, and is also suspected of planning to carry out an attack in Tripoli.
When arrested he is reported to have told Libyan authorities: "I have ideology with my brother... I know everything about my brother, what he was doing there in Manchester."
There was no reason given for the arrest of the bomber's father, Ramadan Abedi, outside his home.
Before his arrest Ramadan had insisted his son Salman was innocent.

CCTV images obtained by Sky News appear to show Abedi buying the rucksack police believe he used to conceal the bomb.
