This probe panel should comprise police officers, advocates and human rights activists among others, party founder S Ramadoss said in a statement here.
He said relatives of those who had gone to Andhra Pradesh to work in the construction industry from Villupuram andDharmapuri districts had complained that their whereabouts were not known even as there were allegations that the red sanders mafia had held many of them as bonded labourers.
Expressing concern over the gunning down of the 20 people by Andhra Pradesh police, he slammed the police personnel for their 'brutality' and criticised the state government for backing them.
He also alleged that the victims were tortured before and after their death, referring to burn marks and other injuries on their bodies.
