According to the alarm it would burn in cardboard boxes, but when you arrived it turned out that someone had lit a grill in a basement room.

However, residents of the house had already extinguished the grill with water. The emergency services only had to remove the grill.

Lighting a barbecue in a basement where a risk of spread could occur can be a crime and is then classified as dangerous carelessness.

"But we have not made any notification in this case," says Åsa Willsund, press officer at the Eastern Police Region.

At the end of August last year, smoke was alerted from the basement at the same address. Then it was a disposable grill that was lit in a storage room.
