On 7th August 1993, a bombing at the Rashtriya Swayamsevak Sangh offices in Chennai, India, killed eleven people and injured seven others. RSS is a Hindu nationalist organisation which is opposed to Muslim separatism.
Several people were arrested in connection with the incident and convicted on the basis of confessions. However, the alleged bombers had confessed to purchasing 13kg of gelatin sticks for the purposes of making a bomb. Tests on the site of the explosion showed that only RDX and PETN were present.
On 6th December 2010 Justice Surinder Singh Nijjar at the Supreme Court of India handed down a judgement setting aside the original convictions:
“the prosecution story as put forward does not inspire confidence on the basis of the material placed on record. Criminal Appeal No.1374 of 2007 and Criminal Appeal No.552 of 2008 filed by the accused appellants are, therefore, allowed and the conviction and sentence passed against the appellants are set aside. They shall be set free forthwith unless wanted in any other case.”
