Schools are warning parents not to let their children watch the Netflix horror series Squid Game after pupils were caught copying scenes in the new show.    

The South Korean series, which is currently the most streamed show in the US and in the UK, centres around a fictional game show in which poverty-stricken characters compete in a series of death games to win a £27million cash prize. 

The survival drama, which features gruesome scenes of characters being shot in the head and organ harvesting, sees contestants take part in versions of traditional children's games, with the winners progressing to the next stage. 

Those failing the tasks are executed by a masked death squad standing by with machine guns.  The controversial show has now left schools urging parents to monitor what their children are watching amid fears of copycat behaviour.
