The man, who is in his 30s, is suspected on probable grounds of a serious violation of the Knife Act and a serious threat against a public servant, the newspaper reports.
His injuries are considered serious but not life-threatening.
"My impression is that he was shot in the leg, I don't know how many times. There is also information that a stun gun was used, but I can't swear that he was hit by it," prosecutor Svante Alm told Mitt i.
The man denies the crime.
The police's actions are being investigated by the Special Prosecution Office.
