The boy went from Halmstad to Hylte when the perpetrators robbed him of his shoes and a keyboard at knifepoint.
The teenage boys, two 17-year-olds and a 15-year-old, are said to have threatened the boy not to tell anyone about the incident.
According to the prosecutor, the crime should be assessed as serious as the teenagers took advantage of the boy’s young age and vulnerable situation. They are charged with aggravated robbery and aggravated assault in court.
The suspects deny any crime.
