- Emiliano Sala was exposed to carbon monoxide before crashing into the English Channel early this year
- The Argentine forward was enroute his new club in a private jet before the ill-fated crash
- Sala became Cardiff City's record signing when he signed a deal with the then Premier League club
Late Argentine striker Emiliano Sala was said to have been exposed to flammable gas (carbon monoxide) before his plane crashed into the English Channel earlier this year.
The 28-year-old became Cardiff City's record signing after joining the then Premier League side in a deal worth £15 million from Nantes in January 2018.
He was enroute to his new club in a private jet with his pilot David Ibbotson before losing control of the aircraft - which eventually led to his untimely death.
However, after toxicology tests were carried out on his body, it was revealed that the late striker was exposed to a high level of CO (58%) - which could have caused seizure and unconsciousness or a heart attack according to BBC.
"A COHb level of more than 50% in an otherwise healthy person is generally considered to be potentially fatal."
Sala family's lawyer Daniel Machover of Hickman & Rose solicitors said the report raised further questions.
"The family believe that a detailed technical examination of the plane is necessary.
"The family and the public need to know how the carbon monoxide was able to enter the cabin. Future air safety rests on knowing as much as possible on this issue."
It would be recalled that Mr Ibbotson's body has not been found seven months into his disappearance after the crash.
But it is likely he would also have been exposed to carbon monoxide, according to Air Accidents Investigations Branch (AAIB) lead inspector Geraint Herbert.
"Symptoms at low exposure levels [to carbon monoxide] can be drowsiness and dizziness, but as the exposure level increases, it can lead to unconsciousness and death," he added.

"The investigation continues to look into a wide range of areas in relation to this accident, but in particular we are looking at the potential ways in which carbon monoxide can enter the cabin in this type of aircraft."
BBC further reported that investigation into the crash is ongoing and may not be ready for publication until early 2020.
The ex-defender was said to have battled Alzheimer disease before finally passing away earlier this week.
Meanwhile, his family was said to have recently admitted that the sickness took a toll on the former footballer before his eventual death on Monday.
