Angelina Jolie and Brad Pitt's baby shower pictures have been returned after police in California arrested a suspected culprit. Photos of the party the couple held in Namibia ahead of the birth of their daughter Shiloh Nouvel last month were snatched. It is thought the thief tried to sell the digital memory card from the pair's camera in the US, before cops swooped on Tuesday. Their spokeswoman Cindy Guagenti confirmed the pictures had been returned and a suspect arrested, but refused to reveal any more information, reports the New York Daily News. Jolie and Pitt had threatened to sue and prosecute any publication that published the pictures, rendering them worthless to magazines and newspapers.
