An explosion occurred on Tuesday evening at a villa in Hällbybrunn in western Eskilstuna.
Several people were in the villa during the incident, but no one is reported to have been injured.
There has been damage to the villa, but it's not about any major damage, says Dick Stegsjö, duty officer at Police Region East.
The police were alerted by several callers shortly after 9:00 pm, but it is still unclear what has exploded.
Yes, we don't know yet, but the area is cordoned off and the national bomb squad is working on it, says Dick Stegsjö.
The incident is being investigated as reckless endangerment and a crime against the law on fire hazardous and explosive materials. No suspect has been arrested.
