Teen questioned over Stockholm explosions

A teenager arrested on suspicion of causing an explosion at a Stockholm school that injured a girl may be behind several other neighborhood blasts, police said. The explosion at the Solbacken preschool was the result of a powerful homemade firecracker and a 4-year-old girl\'s hands were injured in the blast, The Local reported Tuesday. \"The girl found the cracker inside the preschool\'s area. It exploded in her hand,\" Lennart Lofgren of the Stockholm police said. She was operated on at a hospital and is expected to make a complete recovery, doctors said.
