Condition of Hong Kong student injured in car park fall deteriorates, but doctors yet to confirm brain death
- Medical source says pressure formed inside skull of Chow Tsz-lok on the impact of fall has reached a life-threatening level
- Police plan to seek security footage of buildings around car park for more clues on accident

The condition of a Hong Kong university student who was left on life support after falling four metres (13 feet) in a car park on Monday has deteriorated, but doctors have yet to conduct a test to confirm whether brain death has taken place, medical sources have said.
Police on Thursday said they would seek security footage from nearby buildings after a review of more than 30 cameras at the car park failed to establish the cause of Chow Tsz-lok’s fall.
Chow, a 22-year-old student of the Hong Kong University of Science and Technology (HKUST), remained in a critical condition at Queen Elizabeth Hospital on Thursday. He was reported to have fallen from the third floor to the second floor of a car park in Tseung Kwan O during the small hours on Monday.
A medical source said the pressure inside his skull had built up to five times the normal level, a life-threatening condition.
“It could mean the brain would be cut off from blood supply because the pressure prevents blood from going in,” the source said.

Another source confirmed that a brain death test was not conducted on Thursday.
