Several people have been killed in a shooting at a shopping centre in the Danish capital Copenhagen, police say.
Announcing the deaths, police chief Soeren Thomassen said a 22-year-old ethnic Dane” has been arrested in connection with the attack.
Mr Thomassen said the motive was unclear, but that he could not rule out an “act of terrorism”.
Eyewitnesses have spoken of panic among shoppers as gunfire rang out inside the Field’s mall in the south of the city.
Emilie Jeppesen told Jyllands-Posten newspaper: “You didn’t know what was happening. Suddenly there was just chaos everywhere.”
Speaking at a news conference , Mr Thomassen said it was too early to say how many people had been harmed in the attack.
But he told reporters that there was no indication that other shooters were involved and urged shop owners to preserve any video surveillance footage they may have.
Field’s is 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.
British singer Harry Styles is due to perform at a venue less than a mile from the scene later in the evening.
Organisers wrote on Facebook that the concert would go ahead after close co-ordination with police.
