Three banners with swastikas were hung above Essingeleden in Stockholm during the morning, reports Aftonbladet.
Large red flags are hanging over the entire tunnel, says a witness to the newspaper.
The police received the alarm at 07.19 and the banners were taken down at 07.40. Who is behind it is unclear.
We have no one identified at present, says the police's press spokesperson Mats Eriksson to TT.
No report has been filed at present, but the crime classification that is closest is agitation against a group of people, according to Eriksson.
