More than two months after the death of 21 young people in a bar, there is new information about the mysterious circumstances of death.

According to their own statements, the parents of the young people were informed by officials on Thursday that their children had suffocated in the overcrowded bar.

On June 26, 17 bodies were found in the informally run Enyobeni Tavern in a township in East London.

Four other teenagers later died in hospital.

The 21 fatalities were between 14 and 20 years old, eight of them were girls.

Survivors then reported that the bar was crowded, completely overcrowded, and that there was an acrid smell.

Relatives of the victims now said they had been called to the health department to be informed of the results of the final toxicological report.

However, they were then only informed verbally and were not allowed to see the report, citing confidentiality.

Xolani Malangeni, who lost his 17-year-old daughter Esinako, expressed doubts about the report's findings.

Suddenly the doctors gave "suffocation" as the cause of death, said the father, who still does not want to rule out that the young people died of poisoning.

A preliminary toxicology report released in July was inconclusive.

However, the Cape Town laboratory ruled out alcohol or carbon monoxide poisoning as the cause of death.
