The two men were arrested in the vicinity of the Gallerian shopping mall in central Stockholm on Tuesday and the building was evacuated for just over an hour while a police bomb squad removed the object for examination.
A Stockholm police press spokesperson said they would not comment on the matter. When asked by The Local if there was any danger to the public, they replied however that “if we had made that assessment we would have said it”.
Nor would police comment on a report in tabloid Aftonbladet that the suspected explosive was a “hand grenade-like object” found on one of the men while being searched by the mall's security guards.
Sweden has been struggling to crack down on the possession and use of hand grenades and illegal weapons by gangs in recent years, with explosives in circulation dating from the Yugoslav wars.
The Swedish government has proposed an amnesty between October 2018 and January 2019 in an effort to get grenades off Swedish streets.
