A fifth suspect, believed to be carrying a package, has been arrested in Wigan today as detectives probe a "network" linked to the Manchester suicide bomber.
The man was taken into custody in connection with Monday night's attack and officers are assessing the package, Greater Manchester Police said.
Meanwhile, the terrorist's father and brother were detained in Libya while police have confirmed that an off-duty female police officer was among the 22 people killed in the attack.
Libyan security forces said the brother "was aware of all the details" of attack plans.
Chief Constable Ian Hopkins has said officers are investigating associates of Salman Abedi when asked if they are seeking a "bomb maker".
Abedi's father Ramadan has reportedly been detained by Libyan counter terrorism police while recording television interviews, according to ITV News.
It follows an interview in which he denied his son Salman's involvement in the blast and said: "We don't believe in killing innocents. This is not us."
Abedi's younger brother Hashem has also reportedly been arrested in Tripoli, Libya, on suspicion of having links to the Islamic State group that claimed responsibility for the attack.
Abedi Snr warbles "We don't believe in kililng innocents".
Ah yes, typical mohammedan weaselwording. Because how many foolish and gullible western reporters, hearing that, will realize that in the eyes of such as he, a bunch of dirty filthy kuffar whores, tarts, and sluts, all unislamically dressed, living in the Dar al Harb (zone of War) are NOT innocents. They are uncovered meats. They are as-yet-unsubjugated Infidels and as such they deserve to be killed in order to purify planet earth of fitna, corruption and wickedness. The only thing that a pious Sunni Muslim such as Abedi Snr regards as an 'innocent' is a fellow Sunni Muslim of the approved degree of sharia compliance.
Kuffar are guilty by definition.
