A shooting took place in the Field's mall in Copenhagen, Denmark, and left several victims, Danish police said, reporting that the security services arrested one person in connection with the shooting. They, however, did not give details on a potential motive behind the attack.

Police reinforcements have been deployed around the mall in the Amager district between the city center and the airport, Copenhagen police wrote on Twitter. 

Vi er fortsat massivt tilstede i Fields og arbejder på at sikre hele bygningen. Er man fortsat i Fields, så bliv hvor man er og afvent politiet #politidk https://t.co/84Df2mspVD

"We're on the scene, shots were fired and several people have been hit," the police department said. 

Images taken at the scene show women running away with their children and medical crews carrying people away on stretchers.

"Terrible reports of shooting in Fields. We do not yet know for sure how many are injured or dead, but it is very serious," Copenhagen mayor Sophie Andersen said in a post on social media. 

At least three people are being treated at hospitals, public broadcaster DR reported, and eyewitnesses quoted by Danish media said they saw more than 100 people rush toward the exit as soon as the first gunshot echoed through the large shopping center.

Heavily armed police officers prevented onlookers from approaching and locals from returning to their homes. 

Right across the North Sea in Norway, Norwegian police had reported a week ago that two people were killed and 14 others were injured, some critically, in a shooting near bars in central Oslo.

Two deaths and 14 injuries were reported, as well as the seizure of two weapons.
