North Zealand Police officers arrested a man early on Monday that they say intentionally set fire to a residential block in Hillerød.
The arrest occurred after an intense search that included police helicopters, dogs and special agents from the Danish Security and Intelligence Service (PET).
The arrested man is a resident of the burned apartment complex who police considered “dangerous”.
“He was seen with a knife, but he hasn't threatened anyone. But we believe that he can be dangerous and therefore we want to get ahold of him as quickly as possible,” police spokesman Henrik Suhr told news agency Ritzau before the arrest.
The fire was allegedly started in the arrestee's flat before spreading to the rest of the building. All 24 apartments were evacuated but responders were able to get the fire under control before it spread past the roof.
The fire and water damage could mean long delays in getting residents back into their homes.
“There is serious damage to the building and the fire spread through the entire roof. Just the water damage alone can result in it taking time to get people living here again,” Suhr said.
No injuries were reported.
