British authorities raided Amy Winehouse's London apartment yesterday, confiscating several boxes after spending three hours going through her things. It was part of an investigation that led to the arrest of four unidentified men later. "It's part of an ongoing operation," said police. However, drugs were apparently not the reason for the raid. "It has nothing to do with drugs," said a spokesman for the singer. "Amy is fine. She has not been charged or arrested." Unfortunately, her husband, Blake Fielder-Civil didn't get off so easy. He was arrested, along with the other four men, for allegedly attempting to manipulate a witness in his upcoming assault trial and "perverting the course of justice." Blake was due to stand trial on November 12 on charges of assaulting a barman last June.
