"CBI...Could not find sufficient/prosecutable evidence against any of the accused. Subsequent to this, closure report in the case was filed today," the agency said in a statement.
Shetty (39), a Right to Information activist, was stabbed to death on January 13, 2010 as he stepped out of his house in Talegaon near Pune for a morning walk.
The case was transferred to CBI after Shetty's brother Sandeep moved the Bombay High Court. The Pune rural police had arrested six persons before that; all of them are out on bail.
"This case is also said to have some relation with the murder case of Shetty. If new evidence comes to notice, CBI will re-open investigation in the case," the agency said.
When sought the reaction, Sandeep Shetty told PTI that "decision to file closure report is arbitrary and amounts to contempt to the HC directives".
Shetty also alleged that this decision was directly linked to change of government at the Centre.
