ITV News' Luke Hanrahan reports
The parents of Zane Gbangbola have spoken of their pain to ITV London as they continue to wait for answers over their son's death.
The seven-year-old died after suffering a heart attack at their home in Chertsey, Surrey during the floods in February.
His father Kye Gbangbola suffered a cardiac arrest and remains paralysed from the waist down.
"I'm broken literally. I don't know how to assemble any kind of focus on life and what it's about. It's something which is truly just unbearable for us," Mr Gbangbola said.
"No-one should experience going to bed laughing, joking as we always did in our house and wake up like this."
Police, unable to establish what happened to the family, have referred the case to the Home Office who have failed to provide any answers yet.
A Surrey Police statement said: "The investigation into Zane's death remains on-going. A post-mortem examination carried out on Tuesday 11th February did not establish a clear cause of death and we await the results of further tests which are expected to take a number of weeks.
"It would be wrong to speculate on the cause of death at this stage. Officers continue to provide updates to Zane's family. We fully appreciate this is difficult time as we wait for updates."
