Union Law Minister Kiren Rijiju on Friday said no one would be spared if found involved in the Arunachal Pradesh Public Service Commission (APPSC) question paper leak case.

Expressing his concern over the paper leak issue in the assistant engineer (civil) exam this year, Rijiju, who hails from Arunachal Pradesh said the country's premier investigating agency the CBI is investigating the case to unearth the truth behind the scam.

Responding to questions from reporters at Naharlagun, near here, the Union Law minister who represents Arunachal West Parliamentary constituency in the Lok Sabha said, "Investigation should be done strictly against those involved in the job scam which is most distressing for all of us as APPSC is an autonomous body and those working in it should re-think about it and its ongoing chaos."

"I had already spoken to the chief minister after the incident was reported to me and suggested that all the members of the Commission should be held responsible for breaching public trust," Rijiju said.

The union minister said no one should influence the investigation process.

"Let the investigation agency work freely," Rijiju asserted and added that no one should be spared if found involved in the scam.

The alleged paper leak case came to light after a candidate filed a police complaint. More than 400 candidates had appeared for the examination held on August 26 and 27.

In October, the state government handed over the case to CBI. A charge sheet was filed by the investigating agency against 10 accused people at the District and Sessions Court in Yupia near here on December 8.

The case was initially investigated by the Capital police and later transferred to the Special Investigation Cell (SIC) of the state police.
