Father, brother of alleged Manchester bomber detained in Libya

She said Wednesday the investigation is continuing and declined to provide further details about Abedi, whose improvised bomb killed 22 people at a pop concert in Manchester. A woman is arrested during a raid in the Blackley area of Manchester. An eight-year-old, two teenage girls and a 28-year-old man were also identified as among those killed in Monday's attack.

The father and younger brother of the suspect in the Manchester concert bombing have been detained in Libya, where anti-terror authorities said the brother confessed to knowing "all the details" of the deadly plot.

Abedi's family remained a focus, too, with a brother in the United Kingdom and his father and another brother in Libya among those being detained.

Do you believe somebody else put the bomb together, and are you searching for that person?

The senior Abedi denied that his son Salman had links to militants, telling the AP in an interview "we don't believe in killing innocents" before being taken into custody in Libya, along with another son, Hashim.

Home Secretary Amber Rudd, who said Abedi had been known to British security officials, complained Wednesday about USA officials leaking sensitive information about Abedi to the media, saying that could hinder Britain's security services and police.

She added that the police were assessing the package the man was carrying.

Only hours earlier Amber Rudd, the home secretary, had rebuked the USA security services for leaking the bomber's name to American media before it had been made public in Britain, but her warnings appeared to have had no impact.

The release of information in the early stages after an attack can present security issues and hamper the work of security services operating in the country of attack, European intelligence officials told Newsweek after the attack.

The sight of soldiers deploying at London landmarks such as Buckingham Palace and 10 Downing Street underscored the gravity of a threat that was known in general terms before Monday night's explosion but has come sharply into focus in the 48 hours since.

Police hunting a potential terror gang behind have found items significant to the probe into the Manchester Arena bombing, it was revealed Thursday. The UK Foreign Office, Metropolitan Police and Greater Manchester Police had no immediate comment on the reported arrest in Libya.

Chelsea, the title-winning soccer club in England's Premier League, called off a planned victory parade through London.

But Ramadan Abedi said he was sure Salman had not been a member of the terrorist group.

Georgina Callander, 18, an Ariana Grande superfan, also died, her school said, and John Atkinson, a 26-year-old student from Greater Manchester, was killed, according to a local politician.

"The investigation into the terrorist attack in Manchester is large-scale, fast-moving and making good progress", Rowley said.

London police say extra security is being added for major sporting events this weekend including the FA Cup soccer final at Wembley Stadium.

British officials say that have received assurances from US authorities that confidential material will be protected.

Twenty-three people are still receiving critical hospital care after the Manchester Arena suicide bombing.
