It was during the weekend that the police were called to a village outside Luleå due to a violent crime.
The majority of police resources participated in the case, including dog handlers and a police helicopter.
A man in his 50s was later arrested on suspicion of assaulting a relative.
Arrested after the assault
On Tuesday, the man was arrested for extremely serious assault.
Prosecutor Jonas Fjellström believes that there is a risk of continued crime and the investigation could be complicated if the man is released.
The man himself denies wrongdoing.
The man has previously been convicted of a serious crime of violence against a relative in Luleå and has served a longer prison sentence.
He admitted the crime but said he suffered from a serious mental disorder.
