A patrol who would go out for a traffic check, unpacked the entire car and loaded things up on the ground. The cops came to lie down themselves and then they took a picture with a drone.

- It was most like a filing, says Carmen Surber in a comment to SVT.

The picture was posted on Facebook with the text "if you ever wondered what is in a police car".

The press department spread the idea

The picture got a lot of appreciation from the followers and the police press department came up with the idea to challenge others at #tetrischallenge.

After that, the phenomenon began to spread throughout the world, and many have contacted the Canton Police and appreciated their initiative.
