The original inquest ruled 7 year old Zane's death in 2014 was an accident caused by carbon monoxide poisoning from a petrol pump brought by his family to get rid of floodwater after their home near to the former landfill in Chertsey flooded.  

But Zane’s parents Kye Gbangbola and Nicole Lawler have always disputed the inquest findings saying the pump wasn't used.  

They say Zane died after toxins flushed out of the site and into their home. 

Mr Gbangbola, who was paralysed following the incident in 2014, and Ms Lawler, have now obtained Public Health England (PHE) papers which back their long-held claims. 

They are calling for an Independent Inquiry into their son’s death. 

A spokesperson on behalf of the Coroner’s Office has said: “An independent, full, frank and fearless inquest into the death of Zane Gbangbola was concluded in September 2016. The inquest ran for over six weeks, during which time the Coroner heard a substantial amount of evidence including that from in excess of 70 witnesses.

“The Coroner’s detailed explanation of his findings and conclusion has been available since the end of the inquest and can be accessed here.

 “Having considered all the evidence that was before the Court, the Coroner concluded that the cause of Zane’s death was ‘Carbon Monoxide Toxicity’. We would like to offer our sincere condolences to Zane’s family and friends on his tragic death.”
