We believe that we have identified four, but it's a bit difficult to say if some of the drones have been identical, says Asger Bechstrøm, officer in charge at Midt- og Vestsjællands-polisen.
The police received the alarm about the drones at 22.30 on Friday and when a patrol arrived at the area, they saw four drones.
There is a complainant who says that he has seen up to 20 drones. He also has a video where it appears as if there are more drones. But I cannot say anything certain about the number.
The last drones were seen shortly after 1 am, when they disappeared over the sea at high speed, according to the police in a press release on Saturday.
