The Central Bureau of Investigation (CBI) on Sunday arrested two people in the murder case of Congress leader Pavan Raje Nimbalkar.
Nimbalkar and his driver were shot dead in Navi Mumbai in 2006.
After the police failed to make a headway in the case, the Bombay High Court transferred it to the CBI.
One of the arrested has been identified as Mohan Shukl, a retired Central Excise official and BJP corporator from Dombivli.
The other is Satish Mandhade, a businessman from Latur.
Joint Director of CBI (West Zone) Rishi Raj Singh confirmed the arrests. The two will be produced before a Special CBI court on Monday.
Mandhade is known to be close to a very senior state politician who was recently elected as Member of Parliament. The senior politician is said to be the brain behind the killing, said a senior CBI official.
The CBI has already arrested two of Nimbalkar’s killers.
Another senior CBI official, who is not authorised to speak to the media, , said on condition of anonymity that that Mandhade organised the Rs 30-lakh contract money to kill Nimbalkar.
The CBI had on Wednesday recovered the car used in the crime.
