The mother of a boy who died from severe burns said his death had "ripped the family apart".
Seven-year-old Preston Flores from Aberdeen suffered burns to much of his body in an incident believed to have involved petrol.
It is understood the little boy was playing with friends in Bedford Avenue in the east of the city when he was engulfed by flames on Friday afternoon.
He was taken to the Royal Hospital for Sick Children in Edinburgh for specialist treatment but died this morning.
His mother, Luisza, said in a statement: "He meant the world to his family and will always be deeply missed and loved. Preston was a special little boy and his loss has ripped our family apart.
"On behalf of our family, I would like to thank everyone for their support but would ask that we are now allowed to grieve in peace for Preston."
Police responded to reports of a boy on fire on Bedford Avenue at around 2pm.
Officers are investigating whether petrol was involved but say there is no suggestion that the youngster was the victim of a deliberate act.
A spokeswoman did not comment on suggestions that the children accessed fuel from a council vehicle.
Preston was a primary three pupil at Sunnybank School where acting headteacher Michelle McKay said he had lots of friends.
She said: "Preston was a lively and competitive little boy who loved football, PE and all sorts of outdoor activities, as well as board games, baking and building with Lego.
"He was a fun-loving boy with a great sense of humour and lots of friends. He loved his family too, and was always sharing with us the latest news about his new baby brother.
"This is a tragic time for his family, for the school and for everyone connected to it. We are all so saddened by what has happened.
"This is a strong and close-knit community, however, and so we are all supporting each other and I am sure that, together, we will find ways of coming to terms with our loss."
Police said a report will be sent to the procurator fiscal in line with usual procedure.
Detective Inspector Lorna Ferguson, from Police Scotland, said: "Our thoughts are with Preston's family, friends and the Bedford community at this sad time."
Leader of Aberdeen City Council Barney Crockett said: "Preston's tragic death following last week's terrible events have left the local community and the whole city in shock.
"My own thoughts are with the little boy's family, and the whole city council would like to extend our deepest sympathies to them.
"Every support at our disposal is being made available to the family and to Preston's school, and we will continue to provide all the assistance we can through this very difficult time."
A council spokesman said the authority was looking into the circumstances of the incident.
First Minister Alex Salmond said: " This is a tragic time for the young boy's family, for the staff and pupils at Sunnybank School, and for the many friends of Preston Flores. Our thoughts are with them all."
