Muslim extremist Salman Abedi blew himself up at the Manchester Arena in 2017 at the end of pop star Ariana Grande’s concert. Parents came there to pick up their children after the concert. 22 people were killed, including children.
His brother Hashem was sentenced to 55 years in prison in August last year for his part in the attack. And now a 24-year-old suspect has also been arrested who would have helped with the preparations for the attack.
