Porpoise death brings tally of dead dolphins found to six this year
Dead mammal found on Lantau beach becomes latest marine fatality in local waters

A dead finless porpoise was found on a Lantau beach yesterday - at least the sixth dead dolphin found in Hong Kong waters so far this year.
The mammal's body was spotted by swimmers at lower Cheung Sha beach, on the southern coast of Lantau Island.
Police said the swimmers reported seeing the dolphin floating off the rocky beach outside the shark nets after 6am.
The porpoise is about one and a half metres long and it had external injuries.
The Agriculture, Fisheries and Conservation Department was looking into the porpoise's death after an initial investigation by the marine police.
A month ago, a rarer Chinese white dolphin was found dead near Tai O, also on Lantau.
