The inquest into the death of 17 year old Yifan Wang has been told by pathologist Dr. Marek Godlewski the cause of death was drowning even though Wang did not die until a couple of days after being pulled from the swimming pool at the Aquatic Centre.
The inquest also heard there was no indication Wang was sick before he drowned.
There was evidence of bronchial pnuemonia but that is consistent with taking in water and being on a ventilator.
He also had bruising and abrasions which the doctor concluded was caused when Wang was pulled from the pool and given what was described as aggressive CPR.
