MARINE Police were involved in a high seas chase yesterday - to catch a trio of stray dogs deserted on an island off the Shau Kei Wan typhoon shelter. They were called to the scene by officers from the Royal Society for the Prevention of Cruelty to Animals (RSPCA) who had been alerted to the dogs' plight by members of the public. When the rescuers reached the rocky island, however, things didn't go quite as planned. One of the animals was easily captured, but the other two made a bid for freedom by jumping into the sea. The officers were then forced to give chase. The animals are believed to have been abandoned on the island, which sits about 100 metres offshore, by a fishing family. A similar rescue took place on an island off Stanley Beach three months ago when marine police were also involved. One of the animals caught yesterday appeared to be in bad health and might have to be put down, the society said, while the other two, if they are found to be healthy, would be available for adoption.
