Narendra Dabholkar, a well-known activist, was shot dead on August 20, 2013 in Pune.
During investigation into the murder case of rationalist Narendra Dabholkar, the CBI recovered a firearm from a creek in Thane district of Maharashtra, sources in the probe agency said.
The Central Bureau of Investigation (CBI) hired services of a foreign sea explorer agency to search and recover the firearm used in the killing of Narendra Dabholkar.
The CBI earlier claimed in a Pune court that one of the accused shooter, Sharad Kalaskar, dismantled the firearm used in commission of the crime and threw it in a creek in Thane.
"A weapon has been recovered during the search operation, but whether it is related to the crime or not will only be confirmed after the ballistic report from the forensic laboratory," a CBI official said, on condition of anonymity.
He, however, refused to divulge any further details about the recovered weapon.
Advocate Sanjeev Punalekar, one of the accused in the case who was arrested and is currently on bail, is alleged to have advised Sharad Kalaskar to destroy the firearms used in the crime.
Advocate Punalekar, before his arrest, had represented members of the Sanatan Sanstha and other activists in various cases in courts.
The CBI earlier claimed that during the investigation, it came to light that in June 2018, Sharad Kalaskar visited Sanjeev Punalekar's chamber in Mumbai where he explained his role in the killing of Narendra Dabholkar.
"Punalekar then told Kalaskar to destroy the firearms used in the killings, including of journalist Gauri Lankesh (in Bengaluru)," the CBI had earlier claimed in the Pune court.
The agency also told the court that on July 23, 2018, the man dismantled four country-made pistols (by taking out barrels and sliders) and threw them from a bridge in Thane creek while on way to Nallasopara (in adjoining Palghar district) from Pune.
