Police have named British-born Salman Abedi, 22, as the perpetrator behind the bombing at the Ariana Grande concert, Manchester Arena on Monday, attended by thousands of children and teenagers.

 The bombing which took the lives of at least 22people and left about 64people with life-threatening injuries is the deadliest attack in Britain since July 2005, when four British Muslim suicide bombers killed 52 people in coordinated attacks on London’s transport network.

“It seems likely, possible, that he wasn’t doing this on his own,” interior minister Amber Rudd told reporters.

Rudd also said Abedi had been known to security services before the bombing.

She said up to 3,800 soldiers would be deployed on Britain’s streets, freeing up police officers to carry out patrols and investigatory work.
