Abedi made it possible for himself to be explosive

london - The man who had a bomb attack in Manchester on Monday night could have made the explosive used himself. In addition, he may receive help from a handler, said a source with knowledge of the investigation against Reuters.

'The focus is still the search for hangovers and the network, but he can make this bomb himself,' concluded the source. Earlier it was questioned whether attacking officer Salman Abedi himself was able to put together such an explosive.

The concern about potential accomplices led to the threats in Britain being threatened on Tuesday. 'We can not ignore the possibility that a larger group of people were involved in this attack,' said Prime Minister Theresa May.
