On January 7, the Mumbai police had registered an 'Accidental Death Report' (ADR) in connection with Puri's death.
Puri (66), known for his roles in several landmark films such as "Ardha Satya", "City of Joy" and "Aakrosh", died after a heart attack at his apartment in Lokandwala Complex in suburban Andheri here on January 6.
Since he was alone at his house at the time of death and sustained an injury, Oshiwara police registered an ADR as per routine procedure, a senior police officer had said.
