Three juvenile sharks were seen again in Hoi Ha Wan Marine Park of Hong Kong, the Agriculture, Fisheries and Conservation Department of Hong Kong announced Sunday.

Three sharks, three to four feet long each, were sighted by department staff near the Hoi Ha Wan Marine Life Center at 3.45 - 4.45 PM local time.

The department advised people to stop all sorts of water-based activities in Hoi Ha Wan Marine Park.

A department spokesman said people should refrain from swimming, diving or any other water-based activities in the park for the time being, not even in shallow waters.

"For their own safety, people found in the water in the park will be asked by our patrol staff to leave the water immediately," the spokesman said.
