A jewelry shop in Oslo was robbed on Saturday, said the Oslo police on Twitter.

Gunshots were fired when the robbery occurred in the Greenland area of the Norwegian capital city, where many immigrants live and run business. But nobody was injured, said the Oslo police.

A witness accounted that the gunshots sounded like pops from a cannon.

Information on the loss and perpetrators was not immediately known while a police investigation was launched into the incident.

The tense situation on the street near the Toyen school had calmed down somehow now as policemen had taken control of the situation.
