On Monday night, Salman Abedi detonated an improvised explosives device at the Manchester Arena as Ariana Grande was leaving the stage following a concert. He killed himself and 22 more people in the blast, including an eight-year-old child. Over a hundred more people had to be taken to hospital with horrific injuries. He was working for the Islamic State, specifically ISIL, who have claimed responsibility for the worst terrorist attack on the UK since the 7/7 bombings.
What the police are trying to determine now is whether or not Abedi was part of a larger terrorist network, planning the attack.
Mike McCaul, a US Congressman from the Republican Party who is also in charge of the homeland security committee, claims that Abedi used triacetone triperoxide (TATP), the same explosive that was used in the 7/7 attacks on London, as well as the Paris and Brussels attacks by ISIS, in the Manchester Arena bombing.
Abedi only entered the UK days before the attack
It is believed that Abedi came back to UK soil just days before the attack on Monday. It is supposed that he travelled from Libya via Istanbul and Düsseldorf last Thursday. According to Turkish officials, there is no official record of Abedi ever travelling to Syria.
