The alarm came in at 20.30 on Friday evening. The police cannot provide any details about the incident, other than that there is no relationship between the men and the children who were locked in.
Interrogations have been held with the arrested and thereafter the prosecutor has decided to lift the arrest, says Elisabeth Glas, press spokesperson for the police in region Nord.
The preliminary investigation is still ongoing, according to Glas.
No one was physically injured. The suspected men are in their 35-45 years of age and not previously known to the police.
