The national bomb squad has completed the investigation of the suspected hazardous object found on a villa plot in Blomstermåla outside Mönsterås during the night to Friday.
It was some form of pyrotechnics. It can still cause some minor material damage and the bang can be quite powerful, says the police's press spokesperson Evelina Olsson.
A report on attempted general endangerment will be drawn up. The cordons are lifted and the police are clear on the site. No one has been arrested.
