A gunman has killed three people and wounded others, three of them critically, at one of Denmark’s biggest shopping malls, police say.
A 22-year-old man has been arrested and charged with the attack which sparked panic among shoppers at Field’s mall in south Copenhagen.
Police chief Soeren Thomassen said the motive was unclear and he could not rule out an “act of terrorism”.
Prime Minister Mette Frederiksen said Denmark had suffered a cruel attack.
Sending condolences to those who had lost loved ones, she said she wanted to encourage Danes to stand together and support each other in this difficult time.
“Denmark was hit by a cruel attack on Sunday night,” she said. “Several were killed. Even more wounded. Innocent families shopping or eating out. Children, adolescents and adults.”
“Our beautiful and usually so safe capital was changed in a split second,” she added.
Denmark’s royal family said their “deepest sympathy” was with “the victims, their relatives and all those who are affected by the tragedy”.
“We do not yet know the full extent of the tragedy, but it is already clear that more people have lost their lives and that even more have been injured,” said the joint statement by Queen Margrethe, Crown Prince Frederik and Crown Princess Mary.
Police say have said there is no indication that other attackers were involved and urged shop owners to preserve any video surveillance footage they might have.
They described the suspect as an “ethnic Dane”.
Field’s is said to be the largest shopping centre in Denmark, with over 140 shops and restaurants. The multi-storey mall is located on the outskirts of Copenhagen, just across from a subway line that connects to the city centre.
Eyewitnesses spoke of panic among shoppers as gunfire rang out.
Emilie Jeppesen told Jyllands-Posten newspaper: “You didn’t know what was happening. Suddenly there was just chaos everywhere.”
Another witness, Mahdi Al-Wazni, told TV2 that the shooter had carried a “hunting rifle”.
