Pop singer George Michael, one of Princess Diana's favorite singers, was arrested for investigation of engaging in lewd conduct in a park restroom, police said Tuesday. Michael was arrested shortly before 5 p.m. Tuesday outside Will Rogers Park in Santa Monica, CA, after an undercover officer on a crime suppression detail allegedly saw him engaging in a lewd act, Lt. Edward Kreins said. "I can't go into details of the lewd act," said Kreins, who noted that the singer was alone at the time. The British-born Michael gave police his real name, Georgios Kyriacos Panayiotou, and then supplied his stage name when asked if he used any other names, Kreins said. The arresting officer did not recognize the pop star, who identified himself as a singer when asked his occupation at the station, Kreins said. Michael, 34, was booked for investigation of misdemeanor lewd conduct and released after posting $500 bail. He was scheduled for arraignment in Municipal Court on May 5.
