Fascinating footage shows police training drone pilots - in a children's soft play centre.
Lincolnshire Police pilots have been honing their skills by navigating climbing frames, nets and slides at a soft play course.
The force posted footage of one of their DJI Avata drones being followed as it navigated the colourful kid's obstacles last week.
They said the soft play provided "one of the most challenging environments" to test their abilities ahead of search and surveillance operations in the real world.
