Black Sabbath bassist Geezer Butler has offered a $1,000 (£625) reward for information that brings a New York cat killer to justice. The rocker contacted officials at America's Society for the Prevention of Cruelty to Animals (SPCA) and revealed he was keen to help them track down the person who is responsible for the deaths of 25 cats, which were found hanging in bags from a tree in Yonkers last month (Apr14). He says, "It is so tragic that we have human beings among us that are capable of committing such a heinous and heartless crime. Surely there is someone out there that knows who has done this. Please do the right thing and come forward to get this coward off the streets." Butler's contribution has increased the total reward to $25,000 (£15,600).
