The three boys, who are 15, 17 and 18 years old, were arrested on Wednesday after the burglary of an LSS residence in Lindbacken outside Uppsala, suspected of attempted murder, aggravated arson and aggravated robbery.
A person who lived in the group accommodation was stabbed in the arm.
On Thursday, the person had been allowed to come home from the hospital and, according to the group accommodation, is "well" under the circumstances.
In connection with the burglary, there was also a fire in the accommodation where five adults live.
"Worked intensively"
Prosecutor Linn Lööw does not want to go into details about how the suspicions against the teenage boys have changed, with reference to the ongoing investigation.
- To some extent, the suspicions have been strengthened and to some extent they have been anticipated.
We have worked very intensively with this during the days that have been and the picture of the whole thing has become much clearer.
The state of evidence is very good, says Linn Lööw.
She also believes that the risk of the suspects influencing the investigation has decreased.
The investigation will now be continued and further interrogations will be held.
