Sweden frees teen, arrests 3 men in triple murder shooting probe
The teen is no longer a suspect in Tuesday’s shooting that killed 3 youths aged 15 to 20 about 70km (45 miles) north of capital Stockholm

“Suspicions against the 16-year-old have weakened during his time in custody. He is no longer suspected of a crime,” prosecutor Andreas Nyberg said in a statement.
Two men around the ages of 25 and 35 were arrested on Thursday suspected of “incitement to murder”, while a third man in his 20s was arrested overnight Thursday to Friday suspected of murder, the statement said. A fourth man around the age of 45 was arrested on Friday, also suspected of incitement to murder.
Three youths aged 15 to 20 were killed in Tuesday’s shooting in broad daylight at a hair salon in central Uppsala, about 70km (45 miles) north of Stockholm.
The shooting shocked Sweden amid rising concern over gang violence, though police have not confirmed that the shooting was gang-related.

Swedish media have reported that at least one of the dead had connections to a criminal gang, though police have not confirmed those reports.
