Congress MLAs Mohan Markam, Deepak Baij and Santram Netam raised the issue through a calling-attention motion.
Somaru Potam,a 12-year-old boy with speech and hearing impairment, was shot dead by the security forces on the morning of December 16, 2016, the MLAs said.
Markam said that according to the boy's father, Somaru and his three friends ran into the security forces while returning home. The security personnel caught Somaru, tied him to a tree and shot him.
Home Minister Ramsewak Paikra however denied this.
A team of district police and CRPF had launched a search operation when it came under fire from Naxals in Metapal forests, and after the rebels fled, body of an unidentified youth was found on the spot, he said.
Somaru Potam, the deceased, was not 12 years old, the minister claimed.
The High Court ordered another autopsy of the body after Somaru's parents moved the court, while Bijapur collector also ordered a magisterial probe. The matter was now pending before the High Court, said the minister.
the boy and details of cases registered against him.
Netam also asked which Naxal 'dalam' the boy was from.
Paikra said Somaru's age, as per his ration card issued in 2013, was 16, so he must have been 20 years old now. No criminal case was registered against him but he was a member of a Naxal militia, said the minister.
It was not known if he suffered from speech and hearing impairment, the minister added.
Congress MLAs asked how was he branded a Naxal if there was no case against him, and whether the government would pay compensation to his relatives.
Leader of Opposition T S Singhdeo said the ration card can not establish age. If the encounter was proved to be fake, would the government give any financial aid to the family, the Congress leader asked.
The minister maintained that government was waiting for the inquiry report.
Not satisfied, Congress members staged a walk-out.
