A 4-year-old girl fell to death from a public housing block in northern Hong Kong after her father was suspected to have left her and his younger daughter at home on Friday.
Emergency personnel were called to Butterfly Estate on Wu Chui Rd in Tuen Mun at 2.18pm, after receiving a report from a security guard.
"The guard called police after she found the girl unconscious outside Tip Mo House in the estate," a police spokesman said.
The child was taken to Tuen Mun Hospital, where she was certified dead about an hour later.
Investigation showed the incident happened after the girl's father left his daughters at home, according to the police source.
