Brother-in-law claims Prince did not sleep for six days before death

Prince appeared "pale" and "weak" during one of his last public appearances, it has been claimed, amid reports the music superstar stayed awake for 154 hours before his death.

Employees at Electric Fetus record shop in Minneapolis said the musician did not look "in the best shape" when he visited the store five days before he was found at his Paisley Park estate.
