The blood vessels carrying blood supply to the brain stem (which is the seat of respiratory and cardiac centre) got disrupted and this became a cause for immediate cardiac and respiratory arrest.
Besides, the liver was ruptured which caused profuse loss of blood, informed the Health Minister.
The Health Minister added that there have been many famous accident victims of this small but fatal negligence.
In August 1997, Princess Diana of Britain died when the car in which she was speeding crashed against a pillar of an underground pass in Paris.
Later it was confirmed that of the four inmates of the ill-fated car, the lone survivor, bodyguard Trevor Rees Jones, owed his escape to the fact that he wore a seat belt whereas the others – Princess Diana, her fiancé Dodi Fayed and driver Henri Paul – had all neglected wearing it, he stated.
