Cops have revealed Manchester attacker Salman Abedi was living off student loans before orchestrating the horror attack that claimed the lives of 22 people.
In the days after the attack, police arrested 22 people on suspicion of terrorism offenses and said they had rounded up a large part of Abedi's network.
A 19-year-old man is now the only person being held in connection to Britain's investigation into the Manchester Arena suicide bomb attack, after being arrested at an airport. "We do, however, suspect others were either aware or complicit in the knowledge of this attack".

"We don't believe it's a large network, we do believe there may be other arrests in the future", Sky News quoted Russ Jackson, head of counter terrorism policing in the north west of England, as saying. "We do however believe further arrests are possible".
It is said to be liaising with the Crown Prosecution Service (CPS) and Libyan authorities.
Abedi had spent "several hours" in Manchester city centre with his rucksack bomb before heading for Manchester Arena, detonating the device as the concert ended and young fans streamed out.
There were a number of arrests immediately after the attack, including of Abedi's brother, but police later declared they beleived the killer had acted largely alone.
Salman Abedi, 22, carried out the suicide attack.
