New Delhi, Jan 08 (Agencies): The RSS on sent a legal notice to the CBI, accusing it of "deliberately leaking" to the media the reported confession of right-wing activist Swami Aseemanand, the main accused in 2007 Samjhauta Express blast.

The notice termed the leakage of Aseemanand's statement as a "politically motivated" and calculated move to "jeopardise" his reputation and deny him a fair treatment.

"The repeated abuse of authority and misuse of law by you do not only render you liable in law as stated but show also how tainted your investigation is," it stated.

On Friday, Swami Aseemanand, the head of the Vanvasi Kalyan Ashram in Gujarat's Dangs district, has reportedly confessed before a magistrate to his involvement in the February 2007 Samjhauta train blast.

He was arrested on November 19, 2010 for his alleged involvement in the Ajmer, Hyderabad and Samjhauta Express blasts, which took place in 2007.

"By presenting the statement made by Aseemanand in the manner you have contrived shows your fairness is dubious and assessment of facts doctored to suit political purposes," the notice stated.

"It is not only in breach of law but liable in addition under the Contempt of Court Act, 1971 for criminal contempt as the exercise undertaken by you is clearly intended to prejudice the minds of the public by deliberately presenting a statement the truth of which is not established as a fact."

The method of investigation has not only to be "scrupulously straight forward" but "it should also have the appearance of being so," it said.

"Aside from the fact you are bound that no harassment be caused to any person", there should be no "zeal to show good work" has been done and you need to be "absolutely fair and impartial," the notice added.
