After technical evidence, the police were able to arrest a man this weekend.
On Monday, the person was requested to be detained on probable cause for rape of a child, which is the higher degree of suspicion.
The man has previously been convicted of similar crimes.
SVT Nyheter has previously reported that the person was suspected of aggravated rape of a child.
The prosecutor demanded that the man be arrested for aggravated rape of a child, but the district court chose to classify the incident as rape of a child of normal degree.
Earlier, the police had indicated Botkyrka as the place where the suspected crime should have occurred, but the correct place is in Salem.
