A man who was rescued after incorrectly being pronounced dead and put in a mortuary freezer has now died.
The police took him to hospital, where he died on Friday.
He remained there until the next day when undertakers who came to collect his body for the funeral saw he was shaking and realised he was alive.
Kumar was later admitted to hospital in a drowsy condition and later died of lung failure, according to Dr Balajinathan, the dean of the government hospital in Salem, Tamil Nadu.
Balasubramaniam Kumar, 74, was kept in a freezer box for 20 hours when undertakers came to collect the body for the funeral and found that he was still moving and gasping for air. Nearly an hour later, a death certificate was issued declaring it to be a home death based on information given by relatives of the patient. A case against Balasubramania's family members has been registered under section 287 (negligent conduct to endanger human life) and 336 (act endangering life or personal safety of others) of the Indian Penal Code.
Police were called and are now investigating the family for not carrying out a proper medical check before declaring Mr Kumar dead.
According to health authorities, an inquiry has been launched against a private hospital where the patient was last taken for treatment and which issued the death certificate. The wife of the deceased Balasubramanian Kumar (73) died two years ago. They called in the police.
The funeral company said they were told by Balasubramanyam's brother that he had "a signed letter of a doctor regarding his demise".
It is not clear how Mr Balasubramanyam survived the freezing temperatures inside a box for almost 24 hours and whether the private hospital, where he was initially declared dead, was being investigated for the incident.
