According to Danish police, multiple people were killed in a shooting at Field’s shopping mall in Copenhagen, the country’s capital, on Sunday. Police have arrested a 22-year-old Danish male and maintain that the attack could have been “an act of terrorism.” At the moment, it does not appear there were additional shooters, police said. A spokesperson for a Copenhagen hospital said that it was treating a “small group of patients” and had asked additional staff to come in. Photos show a heavy police presence at the mall and shoppers running away from the scene.
