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.
The three victims were found in a hair salon in the city of Uppsala, about 43 miles from Stockholm, the capital. They were between 15 and 20 years old, according to the police, but have not been publicly identified.
The motive was unclear, but the police, which said they responded to reports of “loud bangs” shortly after 5 p.m. on Tuesday, said they were investigating if the shooting had been gang-related.
