Leicester City were furious to see drones being used to spy on their first team training sessions ahead of Friday's Premier League clash with Brighton.
A drone operator persistently flew camera-bearing devices over Brendan Rodger's training camp - presumably to capture footage of stars such as James Maddison, Jamie Vardy and Harvey Barnes - and allegedly refused to leave the area when questioned by security guards.
Online footage has since been revealed on YouTube of the club's security chief threatening to call the police.
