Gunfire in a Copenhagen mall Sunday left several dead and several wounded, Danish police said, adding they had arrested one person in his twenties.
Images from the scene showed parents carrying their children as they fled the building and ambulance personnel carrying people away on stretchers.
“We now know that there are several dead,” Copenhagen police chief Soren Thomassen told a Sunday evening news conference, adding that there were also several wounded.
Thomassen described the apprehended suspect, as a 22-year-old “ethnic Dane”, but said it was too early to establish a motive.
“We investigate it as an act, where we can’t exclude, that it’s terror,” the police chief said.
They had no indication that the man had acted together with others, and police were maintaining an increased presence both around the shopping mall and across Copenhagen, he added.
The attack occurred two days after this year’s Tour de France cycling competition started from Copenhagen, and the Tour organisers released a statement expressing their sympathy.
