"Court of inquires have been conducted and the charges have been found to be baseless," an Army source said here.
The Major belonging to the 3 Corps Intelligence Signal Unit in Jorhat had written to the then Army Chief Gen V K Singh and the Eastern Army Commander alleging that his colleagues had killed three civilians inside the unit's premises.
The matter was also dealt by the then Army Chief and inquiries were launched to look into the matter. The charges were against three officers including a Colonel and two Captains.
The Major-rank officer had written twice to the Army Chief in 2011 and again in January 2012 seeking action against the officers allegedly responsible for the murder of three civilians picked up by the 3 Corps CISU in March 2010.
The 3 Corps Intelligence Signal Unit works under the Dimapur-based 3 Corps.
The case had become a bone of contention between the then Army Chief and the then 3 Corps Commander Lt Gen Dalbir Suhag, who was issued a show cause notice by the former in a related issue.
