Police are investigating the deaths of a 33-year-old man and three-year-old girl in Tuen Mun.

At about 3.50pm, a 28-year-old woman called Police to report that her husband and daughter were found lying unconscious inside their residence at No. 45 Lung Mun Road. A basin with burnt charcoal was found nearby.

The man and his daughter were sent to Tuen Mun Hospital where they were certified dead at 4.48pm and 4.44pm.
