The parents of murdered Paul Erhahon moved him to a new school last year after he was stabbed by bullies, his aunt has said.
The 14-year-old died outside his home after he and a 15-year-old friend were attacked by a gang in Leytonstone, north-east London, on Friday.
Police said a bladed instrument or a knife was used to kill Paul and injure his friend, who remains critically ill.
Police were given an extra 36 hours to question two teenagers aged 13 and 19.
A post-mortem examination on Sunday revealed that Paul died from a stab wound.
Paul's aunt Jackie Mustapha, said her nephew was attacked last year in a "personal quarrel".
"That was why his parents moved him to a new school, to stop him from being bullied," she said.
Speaking of Paul's family she said: "They are a very responsible, loving, close family and they love their kids to bits."
She revealed that Paul's mother, Ivy, was with her son as he lay dying.
She said: "His mum was there kissing him, cuddling him, trying to see if she could revive him.
"Paul was a good boy. He was always in his room, on his PlayStation, enjoying his music.
"I remember him for his closeness. He would always kiss and cuddle me, it was never a hand shake. The whole thing is so shocking.
"When is it going to stop? I hope whoever is responsible for this comes and sees the family and sees what they have done to them. We are all in a terrible state."
Police believe up to 15 youths may have been involved in the Good Friday attack.
Paul and his 15-year-old friend, who has not been named, were both found stabbed repeatedly in Crownfield Road, a few yards from Paul's home.
Police believe the pair had been attacked in the foyer of Gean Court, a block of flats in Langthorne Road, in Leytonstone.
On Sunday churches in the area offered prayers for the boys and their families at Easter services.
Revd Nigel Cowgill asked his congregation at Leyton Trinity Methodist Church to pray for all those involved in the tragedy.
He said: "Little did we know that at the end of Holy Week on Good Friday that a young man less than half a mile from this church was killed.

"I wonder how the family and friends of those young men, particularly Paul's family, will be feeling this morning."
Revd Alison MacKay, who led the Easter service at Leytonstone United Free Church, said something needs to be done about the lack of youth facilities in the area.
Graffiti reading "RIP Paul" has been sprayed near Paul's home.
Many messages have also been sent to his MySpace website page, which he had created under the name Hellrazor.
Police have said they are investigating whether Paul's death was gang-related but are keeping an open mind.
Earlier police asked people living near to where Paul was stabbed to death to search their gardens for the weapon.
The latest attack follows the killing of five other male teenagers in London in the past two months.
