It is still unclear what exploded, but the emergency services confirm that they were on site. However, they were able to leave the area relatively quickly.
The alarm came in around 2:30 a.m. on Saturday night.
It is the second time in just over a day that the police have responded to an explosion alarm in Annelund. Late Thursday evening, a hand grenade was thrown at a gate in the area, and a 13-year-old boy was later taken into custody for suspected involvement in the incident.
