A man suspected of killing at least 22 people and wounding dozens at a concert arena in England "likely" did not act alone, Britain's home secretary said. 


Amber Rudd told public broadcaster BBC on Wednesday that suspected suicide bomber Salem Abedi, a 22-year-old Briton, had been known to security services "up to a point". 


Her comments came as security was being ramped up in the wake of the attack, which was carried out in the northern city of Manchester, England, at the Manchester Arena, on Monday evening. 


The suspect apparently detonated a device in the foyer of the concert venue, following a performance by the American pop star Ariana Grande
