In the early hours of Saturday, a mysterious explosion occurred in a three-story apartment building in Klostergården, Lund.

The blast, which happened around 3:50 AM, caused damage to the stairwell, shattering windows and damaging a door.

Police suspect the use of a homemade explosive device, possibly a 'thermos bomb,' rather than a hand grenade.

No injuries were reported, and the national bomb squad is investigating the incident.

Witnesses reported seeing an individual leaving the scene on an electric scooter.

Authorities are probing any potential links to an earlier explosion in Malmö, though they currently believe the two incidents are unrelated.

A preliminary investigation into public endangerment has been launched, but no arrests have been made yet.
