Police have reclassified a Wan Chai child abuse case as murder after the death of a three-month-old boy at Queen Mary Hospital.

In the evening on April 11, a 28-year-old non-ethnic Chinese man and his 23-year-old wife sent their son to Ruttonjee Hospital. Multiple unusual and suspicious injuries were found on his body.

Investigations showed the man had assaulted the baby and the couple were arrested for ill-treatment or neglect by those in charge of a child or young person. 

The baby was later admitted to Queen Mary Hospital where he was certified dead at 12.51pm yesterday. A post-mortem examination will be conducted to ascertain the cause of his death.
