34-year-old Shankar Rajput who was wanted since 2014, was arrested by Mumbai Crime Branch's Unit-X. On 22 March 2013 following a tip-off, the police officials raided a shop in MIDC where they found 800 litres of kerosene. Shankar was arrested for illegally selling adulterated kerosene where he mixed thinners in the kerosene and sold it in MIDC, Andheri. Following the raid, they also arrested two other accused, Premsingh Rajput and Nahar Rajput. 

An officer stated that it was since then that he was in jail and in 2014 he was released on bail. Initially, he used to attend court hearings but later he avoided the court and was soon out of reach. When the crime branch officials failed to locate him, they informed the court. The court then issued a Non-Bailable Warrant (NBW) against Shankar. During the course of the investigation, police learnt that Premsingh and Nahar used to purchase kerosene in black from a local ration shop, mix a thinner to increase the quantity and later sell it to the MIDC.
