A young mother in Cheung Chau has been arrested on suspicion of killing her two-month-old baby by shaking him violently, causing a bleed on his brain.
The boy was rushed to St. John Hospital on the island on Tuesday after he fell into a coma, according to a police statement. The infant, who had a scar on his face, died at the hospital hours later.

Police arrested the childās 30-year-old mother on Wednesday after tests found he had a brain haemorrhage. Initial investigations showed the full-time mother had shaken her baby, police said.
The woman was charged with murder, while her 31-year-old sister was charged with misleading police.
According to a report in The Sun newspaper, the suspect was unhappy with her husband, who was said to work long hours in a restaurant. The couple got married less than two years ago, the report said.
