People should stop all water-based activities in Hoi Ha Wan Marine Park, the Agriculture, Fisheries & Conservation Department says, following the sighting of two more juvenile sharks today.

A 60-centimetre long shark was sighted by department staff near the Hoi Ha Wan Marine Life Centre at 4.30pm. Shortly after, another juvenile shark about twice its size was sighted nearby.

People should not swim or dive in the park for the time being. For their own safety, people found in the water will be asked to leave the water immediately.
