The unrest began at around 6.30pm on Wednesday evening when a police unit approached the youths and was met with stone-throwing. Four teenage boys were arrested.
The next incident occurred at around 10.30pm when police received a call that school buildings were on fire.
Four teenagers were subsequently arrested in the vicinity of Bussenhus school.
“The material damage to the Bussenhus school is extensive. This is a concern when the school is supposed to open again after the weekend. There is also a nursery school,” said Simon Jonasson, station officer at Stockholm Police.
In total, some 30 young people were reported to have been involved in the violence. They also vandalized parts of the local swimming pool and the Tensta Gymnasium high school.
During the course of the evening up to 21 police units from several precincts across the city were in Tensta. Despite the heavy police presence, the teenagers were able to set alight to several cars at around 12.30pm.
Police confirmed that no injuries were reported during the unrest which tailed off during the early hours of the morning.
