The reason is lack of evidence, prosecutor Andreas Nyberg tells the radio.
Another man who was suspected of a serious weapons offense has also been cleared.
Four people remain in custody on suspicion of involvement in the triple murder, including the suspected murderer. A fifth suspect is at large.
It was at 5 p.m. on April 29 that police were called to a shooting near Vaksala Square in central Uppsala. Inside a barbershop, three people – two teenage boys, 15 and 16 years old, and a man in his 20s – were found shot to death.
One of the boys was a student at an elementary school and another at a high school in the city, according to Uppsala Municipality.
