The latest revelations come as intelligence sharing between the US and the UK resumed after a temporary halt following a series of high-profile leaks to US media of details surrounding the Manchester bombing investigation, which were blamed on US government officials. The row comes as British police stepped up their investigation into a suspected network behind Salman Abedi, a 22-year-old British-born man with Libyan parents who blew himself up on Monday night at the Manchester Arena indoor venue after a concert by U.S. singer Ariana Grande

The singer’s fans are mostly children and teenagers and the explosion killed 22 people, ranging from an eight-year-old schoolgirl to parents who had come to pick up their children. On Thursday, Manchester’s top police official, Chief Constable Ian Hopkins, joined the chorus of criticism, saying that the disclosure “has caused much distress for families that are already suffering terribly with their loss.”

Earlier in the day, the BBC reported that the Manchester police would no longer share details of the investigation with American counterparts. Britain has increased its security threat level to "critical" from "severe" following the attack, May said in a later televised statement, adding that members of the armed forces would boost security at key sites and military personnel might be deployed at public events such as concerts and sports events. In Libya, Abedi's brother -- identified as 20-year-old Hashim Ramadan Abu Qassem al-Abedi -- was arrested Tuesday night on suspicion of links to ISIS, according to a statement from a Tripoli militia known as the Special Deterrence Force. Queen Elizabeth visited the Royal Manchester Children’s Hospital, where some of the casualties have been treated, and was filmed chatting with a girl lying injured on a ward. Paul Dryhurst’s niece Kelly Brewster, 32, is feared to have been killed when she visited the Arena with her sister Claire Booth, and Claire’s daughter Hollie, 11.
British police suspend sharing intelligence with the United States in connection with Monday's Manchester bombing attack for most of the day, after U.S. officials allegedly leak "sensitive information" to The New York Times. British Prime Minister Theresa May emphasized the sensitive nature of said information when she met with U.S. President Donald Trump during their meeting at the NATO summit in Brussels. Trump calls for an investigation into the leaks.
