HandoutThe family of 14-year-old Layton Carr, who died at the scene of a fire at a former industrial estate, have described him as "our bright and beautiful boy".
A blaze broke out at a building on Fairfield Industrial Park in the Bill Quay area of Gateshead on Friday evening.
Eleven boys and three girls, aged between 11 and 14, were arrested on suspicion of manslaughter, and police have confirmed two more boys, aged 12, were also arrested. All 16 children have been released on bail.
In a tribute, Layton's family said: "Layton was your typical 14-year-old lad, a cheeky, happy lad. Despite his cheeky side Layton had an absolute heart of gold and would do anything for anyone."
His family, who also released a picture of the teenager, said "he was loved by all that met him, and it showed".
"He was a family boy that loved his mam and sisters more than anything in the world," they said.
"Layton, we love you more than any words can ever explain. You will be missed more than you'll ever know. Our bright and beautiful boy."
Firefighters were called to the blaze just after 19:50 BST, where crews were met with "a severe fire within a section of one of the buildings".
"As a result of the fire, sadly a person we believe to be 14-year-old Layton Carr was found deceased by our firefighters," a spokesperson for Tyne and Wear Fire and Rescue Service said.
Among those paying tribute were friends and staff at Hebburn Comprehensive School.
Headteacher David Thompson said: "Our school community is heartbroken.
"Layton was a valued and much-loved member of Year 9 and he will be greatly missed by everyone.
"We extend our sincere condolences to Layton's family and loved ones at this incredibly difficult time.
"As a school, we will rally together to support one another through this tragedy."
