Singer Amy Winehouse's London home has become the scene of an ongoing investigation following a police raid on Thursday. The hitmaker has not been arrested and police have not revealed why her Camden house was targeted, although forensic photographers were reportedly seen entering the property. Winehouse and her husband Blake Fielder-Civil were not thought to be at home at the time of the raid. A police spokesman says, "We can confirm there is police activity as part of an ongoing police operation." A spokesman for Winehouse denies drugs are involved in the investigation. He says, "The only thing I can tell you is that it has nothing to do with drugs and that Amy is fine and she has not been charged or arrested." Winehouse and Fielder-Civil were arrested for marijuana possession in Norway last month. Cops did arrest four men, aged from 19 to 25, elsewhere in the same operation on suspicion of perverting the course of justice.
