The police blew up a hand grenade during the night towards Friday after a private individual alerted them to a suspicious object at the entrance to an apartment building in southern Malmö, reports Aftonbladet.
We quite quickly saw that it looked like a hand grenade, said Jerker Olsson, duty officer at the police's regional command center, to the newspaper.
The controlled detonation was carried out after the people living closest to the object were evacuated and others were told to stay indoors.
No one has been arrested in the matter.
