A five-year-old girl who suffered a cardiac arrest during a suturing procedure at Yan Chai Hospital last May has died, the Hospital Authority said on Wednesday.

Lai Sum-yuet had been in intensive care in Princess Margaret Hospital since her heart stopped beating for 18 minutes while she was being given stitches for a head wound.

Two staff members were later charged with ill-treatment or neglect over the incident.

A spokesman for the Kowloon West hospital cluster said the girl's condition deteriorated earlier this week and she died on Wednesday morning.

The spokesman expressed deep sadness over the death, adding that the cluster will do what it can to help the girl's family.

"The hospital cluster takes this incident very seriously and will fully cooperate with relevant judicial proceedings. The case has been referred to the coroner for follow-up," the spokesman said.
