“The person who reported the incident says it is a hand grenade. We are not taking any risks until bomb technicians have investigated the object,” said Albin Näverberg of the Stockholm police to newspaper Dagens Nyheter (DN).
Police officers were alerted to the discovery of the object around 11am on Tuesday and bomb technicians soon arrived on the scene.
After having made a first evaluation of the situation, most indications point to it being a live grenade, according to the paper.
“They have made the judgement that there is no immediate danger at the moment. ‘No immediate danger’ I take as confirmation that it was an identified dangerous object,” said Näverberg to DN.
“If you find a live grenade you can say it is ‘no immediate danger’. Unidentified objects are worse.”
A forensic investigation is also underway, according to DN.
The office where the grenade was found has not been under threat from anywhere before, but police told the paper that there are some “special circumstances” that need to be taken into consideration in the investigation.
At 1.30pm, TT reported that the grenade was safely taken from the area in a bomb vehicle and will be investigated further.
