Nasik, Jan 26 (Agencies): Seven persons, arrested for burning to death Additional District Collector Yashwant Sonawane in Nashik district, were produced before local court at Manmad on Wednesday.

Kin demand CBI probe
Brother-in-law of Additional Collector Yashwant Sonawane, killed by oil mafia in Nashik district on Tuesday, has demanded a CBI inquiry into the incident.

"Sonawane's Personal Assistant (PA) as well as the driver was there when the incident occurred. It is surprising that only he was targeted," Anand Dani, brother-in-law of the slain Maharashtra civil service officer, said.

Mobile phone records of Sonawane should be checked and the probe should be handed over to CBI, Dani said.

Meanwhile, Leader of Opposition in legislative assembly, Eknath Khadse, held Food and Civil Supplies department responsible for the incident.

"Two months ago Food and civil supplies Minister Anil Deshmukh carried out the farce of conducting raids (on oil mafia)," Khadse said.

Republican Party of India Leader and former MP Prakash Ambedkar also demanded a CBI inquiry into the incident.

BJP too demands CBI probe
The BJP on Wednesday expressed shock over the immolation of an additional district collector near Nashik allegedly by the oil mafia and demanded a CBI probe to unearth the "nexus of the cartel with bureaucrats and politicians".

"This is a dastarly act. It is shocking and we condemn it. Oil mafias have dared to do such a thing due to patronage they enjoy from ruling politicians and bureaucrats," BJP spokeperson Prakash Javadekar said here.
