The main hearing began on Wednesday behind closed doors, and after three days the Luleå district court decided that the woman should be released.
There shall no longer be any reasonable grounds for detention.
The evidence during the trial included conversations between the woman and the plaintiff via the Snapchat app and logged Facetime conversations.
As SVT previously told, the suspected crimes must have taken place in connection with leisure activities and the woman must have come into contact with the children through her work role.
It was in August that the woman was arrested on probable cause on suspicion of two cases of gross sexual abuse and one case of child rape.
She then denied all crimes and after the main hearing, the position is unchanged.
