A 16-year-old boy was arrested on suspicion of murder in Sweden, the authorities said on Wednesday, after three people were fatally shot the day before, in the latest blow to a country grappling with high levels of gun violence compared to its European peers.

Swedish police have arrested a teenager after a fatal triple shooting in the city of Uppsala on Tuesday. The shooter reportedly fled on a scooter following the attack in a hair salon in the centre of the city, triggering a manhunt. Police confirmed on Wednesday that the person arrested for the shooting is under the age of 18.
