A four-year-old girl fell to her death on Monday from the fifth-story rooftop of an apartment block in Yuen Long, in Hong Kong’s New Territories. The girl had been living with her parents, aged around 40, an elder sister and grandparents in an apartment on the fourth floor in a private residential estate on Castle Peak Road in Ping Shan, Headline Daily reported.

At 5:30pm, the grandmother went to the rooftop to do chores, unaware that the child had followed her.

After finishing the chores, the grandmother went back to the apartment, inadvertently leaving the little girl alone on the rooftop.

Less than 10 minutes later, the girl was found lying unconscious on a  first-floor platform. Police and paramedics arrived and sent the girl to Pok Oi Hospital for resuscitation, but she was pronounced dead at the hospital later.

Initial investigation found that there were two stools on the rooftop. Officers believed that the girl panicked when she was left alone and tried to climb on to one of the stools to look for her parents, but then fell.

Wong Chiu-ling, acting director of Against Child Abuse, said children aged two to five liked to run around to explore, and adults should never leave them unattended. She said windows and doors must be locked to avoid misadventures by children, and also advised parents to avoid placing any objects such as chairs next to a window or on a rooftop, Sing Tao Daily reported.
