Horrific new photos have emerged of the burnt-out hyperbaric chamber which exploded while a five-year-old boy was trapped inside.

Thomas Cooper died when the pressurized oxygen chamber he was inside at a Michigan medical facility burst into flames on January 31.

On Monday, Fieger Law filed a $100million lawsuit on behalf of Thomas's family against the company responsible for the hyperbaric chamber, the Oxford Center.

The firm displayed images during a press conference of the charred chamber and gurney bed, which is now in their possession.

The graphic pictures, shared by Local 4 Detroit show the burnt out remains of the metal frames littered with debris from the explosion.
