Police arrest six in relation to Manchester attack

Among the 22 killed and 64 injured were several children, who had gone to see their favourite American pop singer, Ariana Grande.

If confirmed, the halt to the sharing investigative details with Britain's most important defence and security ally would underscore the level of anger in Britain at leaks to the USA media of details about the police investigation.

They said one thread of the inquiry involved pursuing whether Abedi was part of a larger terror cell that included Mohamed Abrini, otherwise known as "the man in the hat", with connections to the Brussels and Paris attacks.

Manchester police are hunting down a network they think orchestrated the bombing, and the suspected perpetrator's father and brother were arrested in Tripoli.

Flowers and messages of condolence are left for the victims of the Manchester Arena attack.

United Kingdom police said late Wednesday that leaks to American media amounted to a breach of trust and undermined their investigation into the attack, stepping up criticism earlier from Home Secretary Amber Rudd.

On Wednesday, Rudd said she found the leaks "irritating" and expressed confidence that they would end. Those include Abedi's brother Ismail, his father Ramadan Abedi told The Associated Press.

Britain on Tuesday raised its threat level from terrorism to "critical" amid concerns that the 22-year-old Abedi may have accomplices who are planning another attack.

A spokesperson for the Libyan authorities told BBC: "His brother felt there was something going on there in Manchester and he thought his brother would do something like bombing or attack".

In 2011, Abedi returned to Libya during the mass uprising that descended into a civil war and ended with Gadhafi's ouster and death.

The elder Abedi was allegedly a member of the al-Qaida-backed Libyan Islamic Fighting group in the 1990s, according to a former Libyan security official, Abdel-Basit Haroun.

Information in so-called "IS Files" - a huge cache of documents obtained by "Sky News" - shows how an ISIS fighter called Raphael Hostey, from Moss Side in the south of Manchester, sponsored hundreds of terror recruits.

A British official told The Associated Press on Thursday that police in Manchester have chose to stop sharing information about their bombing investigation with the US until they get a guarantee that there will be no more leaks to the media.

Authorities believe he had help in building the bomb, which photographs published by the New York Times, showed was sophisticated and powerful, and that his accomplices could be ready to strike again.
