National Pumps Protection Group investigated the site overnight. Initially, it is unclear if the blast has any connection to the blast at a gateway to a traffic school in Persborg, the night until Saturday. It is only about 500 meters between places.
"It's too early to comment on this, but I'm convinced researchers will look more closely," says Jimmy Modin.
The alarm about the explosion on Sunday night came from several callers who heard a loud bang just before 10:30 p.m.
Later in the night, police were alerted to an alleged firefight in Lodgatan, Malmö, and the patrol, which appeared, found a shotgun on the facade of the building, which houses a taxi office. The same office was housed earlier, but police suspect it is a new shotgun.
