The relatives of three out of the seven victims, who died during the anti-Sterlite protest, refused to accept the bodies.
The relatives demanded for a shut down of the Sterlite plant legally, and also a memorial for the victims.
The post-mortem of the victims was conducted again on the order of the Madras High Court.
Agitations against Sterlite industries have been going on for months now, with people demanding a ban on it due to the various environmental threats it posed.
The protests took a violent turn on May 22 when police opened fire on the protesters, which resulted in the death of 13 people and injuring 102.
