U.K. police said Friday that they are “relieved and overjoyed” to learn that a teenager found walking along a road in southwestern France is a British boy who went missing six years ago. Greater Manchester Police said the teen claiming to be 17-year-old Alex Batty had held a video call with his grandmother, Susan Caruana. "Whilst she is content that this is indeed Alex, we have further checks to do when he returns to the United Kingdom,” Assistant Chief Constable Chris Sykes said.
