A large force of police officers has been sent to the Sandholm refugee and asylum centre where fighting has broken out among some 100 people, some of whom have been using knives.
"We are currently trying to get things under control and get an overview of the situation," says North Zealand Police Spokesman Henrik Suhr, adding that those involved in the fighting are refugees and asylum seekers.
According to eb.dk, at least one person has been killed in the fighting, but it is not yet clear what started the incident.
Although Suhr has declined to confirm or deny any deaths, he says that several people have been seriously injured.
At least four people have been arrested.
