New arrests in Manchester amid extensive investigation into May 22 attack

England’s MI5 – the country’s security service- is to hold an inquiry into the way it dealt with warnings from the public that the Manchester suicide bomber, Salman Abedi, was a potential threat, BBC reported.

Whitehall officials have acknowledged the security service will examine what assumptions had been made about the 22-year-old before last Monday’s attack. It later emerged it was alerted to his extremist views at least three times. Early on Monday a man, 23, was arrested in Shoreham-by-Sea, West Sussex, on suspicion of terrorism offences. Greater Manchester Police said they had also executed search warrants at addresses in the Whalley Range area of Manchester and in Chester overnight.

Seven children were among the 22 people who died when Abedi detonated a bomb on 22 May at the end of a concert by US singer Ariana Grande at Manchester Arena. In all, 14 men are now being questioned in connection with the investigation into the attack. On Sunday, two men were arrested in Manchester – a 19-year-old man in Gorton and a 25-year-old man in the Old Trafford area.
