Police on Thursday said they arrested two men in the Manchester area in connection with the deadly bombing, while a detained woman was released without charges.
The arrests of eight suspects still in custody on Thursday are "significant" in the investigation of the network behind the Manchester Arena terrorist attack, Greater Manchester Police Chief Constable Ian Hopkins said.
Another sibling, 18-year-old brother Hashim, and Abedi's father were arrested in Tripoli on Wednesday.
British police have temporarily stopped sharing some information with the United States about the Manchester terror investigation following a string of leaks by USA officials to the media.
The Guardian and ITV News reported that UK Prime Minister Theresa May was going to raise the issue with US President Donald Trump at a North Atlantic Treaty Organisation summit in Brussels on Thursday. It said the database was built around a longstanding U.S.
British officials were infuriated on Wednesday when the New York Times published forensic photographs of sophisticated bomb parts that United Kingdom authorities fear could complicate the expanding investigation into the lethal blast in which six further arrests have been made in the United Kingdom and two more in Libya.
It came after the name of bomber Salman Abedi was leaked to U.S. media just hours after the attack, which killed 22 - including children - and injured 64.
Authorities say the suicide bomber, 22-year-old British-Libyan Salman Abedi, did not act alone.
The BBC reported Thursday that Britain had stopped sharing information with United States law enforcement "because of a series of leaks thought to have come from the American intelligence community".
Following May's remarks, Trump offered his reaction and vowed that his administration "will get to the bottom of this" and that "the culprit should be prosecuted to the fullest extent of the law". Within hours of sending this evidence to American authorities, these pictures appeared in the New York Times.
May said this meant the independent body which sets the threat level had decided it should be lowered from its highest rating "critical", which meant an attack could be imminent, to "severe".
Thousands of people observed a one-minute silence at 11 am (1000 GMT) in Manchester, London and other British cities on Thursday to remember the victims of the attack. "Very wicked, to target that sort of thing".
Fifteen-year-old Millie Robson, wearing one of Grande's T-shirts, told the queen she had won VIP tickets to the pop star's concert.
Abedi died in Monday's blast at an Ariana Grande concert.
The teenager credited her father's quick action in picking her up and tying off her wounds to stem the bleeding.
The attack injured 116 people, of whom 75 were admitted to hospital and 23 remain in a very serious condition, health authorities said.
In Berlin, former U.S. President Barack Obama and German Chancellor Angela Merkel sent a message of solidarity to the Manchester bombing victims.
"(This is) a reminder that there is great danger and terrorism and people who would do great harm to others just because they're different", Obama said.
It has since emerged that Abedi was known to security services and his risk to the public was listed as "subject to review" ahead of the attack. The photographs also showed nuts and screws for shrapnel and a blue and black Karrimor rucksack that appeared to be carried by Abedi.
