Santosh Singh, accused in the Priyadarshani Mattoo murder case, on Tuesday refuted all charges levelled by CBI and claimed that the investigating agency had tampered with the evidence to prove its case against him.
Appearing before a Division Bench of the Delhi High Court comprising Justice RS Sodhi and Justice PK Bhasin, Defence Counsel RK Naseem claimed that there was no link to form a chain of evidence to prove the case against his client.
He was countering prosecution's stand that it had enough circumstantial evidence to hold the accused guilty of committing the offence of rape and murder.
"Each and every circumstantial evidence has to be conclusively established," Naseem said and alleged that the "CBI in collaboration with the police had tampered the evidence between the period of January 25 to January 28, 1996."
Naseem pointed out that as per records, evidences like blood stains, nail scraps and the hair in the jacket of the deceased were lifted from the place of incident and the same were sealed in a brown envelope. However, the same were later found in three different sealed envelopes, he claimed.
Opposing CBI's argument that broken visor pieces of the accused's helmet were found from the blood stains lifted from the incident spot, Naseem argued that as per the evidence on record the broken pieces are not of visor but of a glass.
"The investigating agency had collected some black coloured visor pieces from Nelson Mandela Road and claimed that these visor pieces are of Singh's helmet, which is a fabrication of evidence," he added.
