Traumatised witnesses have told how nuts and bolts tore into the young music fans when the bomb was detonated in the foyer of the Manchester Arena moments after USA popstar Grande left the stage.
Suicide bomber Salman Abedi may have carried the powerful explosive used in the terror attack on Manchester Arena in a lightweight metal container concealed within either a black vest or a blue Karrimor backpack, according to reports published by The New York Times. They also said that seeing the show that night was "a dream come true to her".
At least 22 people were killed and 59 injured after a bomb exploded outside the Manchester Arena on Monday night, as concertgoers - many of them children and young people - were leaving an Ariana Grande show.
The Islamic State terrorist group has claimed responsibility for the attack.
"Due to the tragic events in Manchester, the Dangerous Woman Tour with Ariana Grande has been suspended until we can further assess the situation and pay our proper respects to those lost", Grande's team said in a new statement to Entertainment Weekly.
Salman Abedi's brother, 18-year-old Hashim Abedi, was arrested Tuesday evening by Rada, a local counter-terrorism force, on suspicion of having links to ISIS, Rada spokesman Ahmed Bin Salem told Reuters. Four people have been arrested, including the bomber's 23-year-old brother.
There was no information released on the man who was arrested.
"I checked his two passports and there wasn't anything in them, he didn't travel to Syria", he said.
Security services believe the suspected bomber, Salman Abedi, was likely to have had help from others in staging the attack that killed 22 people including a girl aged just eight.
But in the early hours of Wednesday Charlotte Campbell revealed her daughter had died in the blast. Rudd said Britain's operational security could be harmed by the leaks, taking "the element of surprise" away from security services and police. "I have been very clear with our friends that that should not happen again".
Jon Rouse of the Greater Manchester Health and Social Care Partnership said there were 20 people still in "critical care" across Manchester by Wednesday at 8.30am, whose "horrific injuries" include major organ damage and potential loss of limbs.
The attack has prompted soul-searching in Britain's Muslim communities about homegrown radicals, as well as concerns about a possible backlash.
