Teen suspect arrested after 3 people shot dead at hair salon in Sweden

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 a day before the Valborg spring festival in the university city of Uppsala, which draws more than 100,000 people for bonfires and celebrations, many of them students.

"One person has been arrested suspected of murder," police commander Erik Akerlund told reporters Wednesday, with prosecutors saying the suspect was 16.
