In addition to the suspicions concerning the riot, the man is also suspected of sabotage against blue light activities on 30 August at Kroksbäck in Malmö and attempted sabotage against blue light activities at Rättscentrum Malmö on an earlier occasion in August.
The man is suspected for probable cause, which is the higher degree of suspicion.
The man was arrested on Wednesday after being arrested in his absence the day before.
On Friday afternoon, arrest hearings will be held in Malmö District Court.
It is not known how the 31-year-old reacts to the accusations.
- I can not comment on it, says the man's lawyer Eva Bazo.
She also does not want to leave any other comments.
In addition to the 31-year-old, another five people have been notified of suspicion of involvement in the riots, several of them minors.
