Contestants on Netflix’s Squid Game: The Challenge are seeking compensation for injuries they allegedly suffered on the show, their lawyers said.

Express Solicitors is representing two players who it says “suffered injuries such as hypothermia and nerve damage”.

Players competed for a KSh. 699.6M (£3.63m) prize on the spin-off show, based on the hit South Korean drama Squid Game.

A show spokesperson said in a statement: “We take the welfare of our contestants extremely seriously.”

Express Solicitors claimed the unnamed contestants suffered the injuries when “they had to stay motionless for hours in cold temperatures while filming”.

Daniel Slade, CEO of the UK firm, said: “Contestants thought they were taking part in something fun and those injured did not expect to suffer as they did.

“Now they have been left with injuries after spending time being stuck in painful stress positions in cold temperatures.

“We have a case where someone complains of hypothermia. One had his hands turn purple from the cold.”

The law firm said it has sent letters of claim to Studio Lambert outlining their clients’ alleged injuries it says were “a result of poor health and safety standards on set”.

A letter of claim is a step before legal action – putting a person or organisation on notice court proceedings may be brought against them.
