Mandade (of Latur), Mohan A. Shukla (Dombivli) and Parasmal Tarachand Jain alias Badala (both of Dombivli), Dinesh R Tiwari, Kailash Yadav and Gyanendra alias Chhote Pandey (both from Uttar Pradesh), Pintoo Singh (Siwan, Bihar), and Shashikant Kulkarni (Mumbai).
The CBI said that in 2005, Patil hatched a criminal conspiracy with Mandade and Shukla to eliminate Nimbalkar who had become a threat to his political career.
Patil's son Rana Jagjitsinh Patil has been nominated an NCP candidate from Osmanabad town assembly constituency for the ensuing elections in Maharashtra.
He will be pitted against Shiv Sena's Omraje Nimbalkar, the son of Nimbalkar.
It is not yet known whether Patil will campaign for his son contesting the Oct. 13 assembly elections in Osmanabad constituency which has been his bastion for several decades.
