Ocean Park Six hammerhead sharks at Ocean Park died in just seven hours because of a disease the park could not identify. The sharks were first found "swimming abnormally" in the Grand Aquarium. Staff moved them to a different area for treatment and observation, but they all died. Later in the week it was revealed that 80 bluefin tuna died two months ago, but the deaths were not reported at the time. The English language The English-language skills of Hong Kong's adult population were said to have slumped to the level of South Korea, Indonesia and Japan. Experts put the blame partly on the switch from teaching mainly in English to mainly in Chinese since the handover. While mainland China ranked 34th, its English skills have been improving. Rob Ford Toronto Mayor Rob Ford admitted that he smoked crack cocaine when he was in a "drunken stupor", but he refused to resign, despite immense pressure to step aside as leader of Canada's largest city. Police said they had recovered a video showing Ford taking the drugs. Two days later another video of Ford emerged, showing him swearing and threatening to kill an unidentified person.
