Three boys, a 15-year-old and a 16-year-old from Wiltshire and a 15-year-old from Dorset, were arrested on Sunday on suspicion of murder.
Detective Inspector Mark Newbury, of Avon and Somerset Police, said: “Mikey’s family have been informed of these events and our thoughts continue to be with them as they come to terms with their loss.
“Specialist family liaison officers supported them through the formal identification process, which is something no family should have to experience.”
He said police were working “tirelessly to piece together what happened”.
A cordon is being maintained at the scene and anyone with images, video or information is being asked to get in touch.
