Taradale Primary School is still working with government agencies to determine how a boy was left hanging by his shirt from a toilet window, critically injuring him.
Aryan Banerjee, 9, was in a stable condition at Auckland's Starship Hospital yesterday, a hospital spokesman said.
It is understood he remains unconscious and may have suffered brain damage. He was transferred to Hawke's Bay Hospital last month, but returned to Starship last week after complications arose.
Aryan was jumping out of a toilet window at the school when his shirt got caught, causing breathing difficulties. He was placed in an induced coma and flown to Starship on May 25.
Aryan's father, a Hawke's Bay GP, reportedly said an MRI scan revealed his son had received significant brain damage. The school was left reeling after the accident, and shaken pupils were offered specialist support services.
