An inquest into the death of university student Chow Tsz-lok during last year's anti-government protests was adjourned on Thursday after the coroner said he discovered "a very important image" from security camera footage.
David Ko said footage shot from outside Kwong Ming Court in Tseung Kwan O, opposite the street from the car park where Chow was found to be seriously hurt in the small hours of November 4, 2019, contained an image that may affect the testimony of upcoming expert witnesses.
Ko said he found the image after going through security camera footage that had not been shown in court.
On Wednesday, a police officer who'd checked the footage told the court that it did not show the car park.
Meanwhile, an emergency doctor who treated Chow said the student might have lost consciousness even before an apparent fall in the car park.
Dr Ray Leung from Queen Elizabeth Hospital told the coroner that people would normally use their arms to protect their bodies in a fall, but there were no bruises on Chow's limbs.
He said that was rare, and that he might have passed out earlier.
Leung added that Chow's head was most severely injured, possibly because he fell from height or was hit by a hard object.
The doctor also said that the 22-year-old's injuries were so serious that it would not have made any difference had he arrived in hospital sooner.
Leung also said Chow had not suffered any burns, nor were there signs that he had inhaled tear gas.
The hearing is set to resume on Friday.
