A reward for information over the crime has been doubled to 100,000 Canadian dollars (US$87,000; £55,000), according to the The News website . Needles were first found in the potatoes at the start of October, and the Royal Canadian Mounted Police says it seems they were shoved into the flesh deliberately. Ten affected potatoes have been found so far, all of which came from the same farm in the eastern province of Prince Edward Island. An initial cash reward of 50,000 Canadian dollars didn't help solve the case, so the region's potato industry and local government have upped the amount, and say even anonymous tips will be eligible for the reward.
