Swedish police have arrested a teen suspect after three youths aged from 15 to 20 were killed in a shooting at a hair salon, authorities said Wednesday, amid rising concern over gang violence in the Scandinavian nation.
Tuesday's shooting took place in broad daylight in the university city of Uppsala, a day before it hosted the Valborg spring festival, which draws more than 100,000 people for bonfires and celebrations in the streets, many of them students.
