“Jay was a much-loved son, brother, uncle, grandson, nephew, cousin and a friend to many. We were all looking forward to celebrating his milestone 16th birthday in August.
“He was a quiet boy with a heart of gold, who would do anything for anyone. He loved playing computer games and riding on his bike and always had a cheeky smile that would light up a room wherever he went.
“We would like to thank everyone who has sent us messages of condolence and all our family and friends who are supporting us through this difficult time. Although we are overwhelmed by the support we are receiving, we would now appreciate privacy to grieve our loss.
“Jay, you will always be in our hearts. Fly high son, until we meet again.”
