An IPS officer, who was appointed by the Gauhati High Court to probe the multi-crore PDS scam in Arunachal Pradesh in 2008, has gone missing while he was on his way to Tawang from Itanagar.

M S Chauhan, Superintendent of Police of the Special Investigation Cell(SIC) in the state police, went missing from Tippi in West Kameng district of Arunachal Pradesh yesterday at around 2.30 PM when he was proceeding towards the Buddhist monastery town, police said on Wednesday.

Mr. Chauhan asked inspector Mohan Kaye and constable Vikram Singh of the SIC, who were accompanying the officer, to drop him at Tippi market and wait for him at a nearby river where he would join them for lunch, police said.

There was no information of his whereabouts since then, West Kameng SP T T Lama said.

The SP, however, ruled out any possibility of his being kidnapped, suggesting that the place where Chauhan got down from the vehicle was a busy area.

“We have launched a search since last night, but no clue on his whereabouts has yet emerged,” Mr. Lama said.

A case has been registered in the Bhalukpong police station.

The Gauhati High Court had appointed Chauhan as the special investigating officer of the multi-crore PDS scam in Arunachal Pradesh in 2008.

Chief Minister Nabam Tuki recently told the state Assembly that the SIC had entered the final stage of its probe.

The SIC has found 64 persons to be involved in the case so far and chargesheets have been submitted against them.
