"A package has been received, a bag with unknown contents. We are going to identify the contents and are in the process of blocking off the area," says Andreas Håkansson, duty officer at the rescue service, to Borås Tidning.
According to the police, it is some kind of suspected dangerous substance.
It concerns a warehouse, where a package or similar with some kind of powder was found, says Fredrik Svedemyr, press spokesperson for the police.
Those who were in the premises have been asked to leave and we have cordoned off the area while waiting for the emergency services to assess it.
