UPDATE 1-No explosives in package outside Swedish police station

Swedish police found no explosives in a suspicious object outside a police station in the southern Swedish town of Linkoping on Wednesday, days after an unexplained blast rocked a local street.

Police said the bomb squad shot at the "package-like" object without it detonating. On Friday, an explosion on a residential street in Linkoping damaged several buildings and left around 20 people with minor injuries. There have been several cases in recent years of explosives used in suspected gang-related attacks, and police are investigating whether Friday's blast was connected to local criminal groups.
