Dutch police have arrested twin brothers on suspicion of robbery after their alleged victim spotted a picture of them following him on Google's Street View map application, a spokesman said Friday. Paul Heidanus, a police spokesman in the town of Groningen, said he believed it was the first time Street View images had been used in a Dutch criminal investigation. "For us, it is unique," he said. A 14-year-old boy told police last September he had been robbed of $230 and his cell phone after two men dragged him off his bicycle. The victim called again in March after seeing an image of himself and two men he believed were his attackers on Street View, police said. Heidanus said prosecutors sent a formal request to Google for the original photo because people's faces are blurred on Street View. "You must tell Google clearly why you want them," Heidanus said of the photo request. In this case, "the photo could provide an important contribution to solving a crime."
