Several people heard the loud bang at Östermalm in central Stockholm and the police were alerted to the address on Grevgatan.
– Something has melted but it is unclear what, says police spokesperson Susanna Rinaldo.
The alarm came in at 19.53 on Saturday evening.
– I heard the bang, it was strong. It continues to sound and there are a lot of police sirens there, says a witness to TV4 Nyheterna.
“Thought the gate detonated”
The police have now cordoned off the area. There is no information about personal injuries, nor whether the National bomb shelter will be called.
– A woman who lives in a house 100 meters from the scene was scared and thought something had detonated at her gate, says reporter Filippa Fernqvist.
