The slain gangsters Ranjan Pathak (25), Bimlesh Mahto (25), Manish Pathak (33) and Aman Thakur (21) – all wanted for multiple murders and extortion among other crimes – were reportedly hiding in Delhi for several days.
Senior officials from the Delhi and Bihar Police visited the encounter site, while forensic and crime scene investigation teams, too, were deployed.
What is the ‘Sigma and Company’ gang?
According to the police, gang kingpin Ranjan operated an organised criminal network in parts of Bihar, particularly in districts bordering Nepal, such as Sitamarhi and Darbhanga, and adjoining states. His gang, also known as the ‘Sigma and Company’, had been active for the past seven years.
They were allegedly responsible for a series of high-profile killings, including that of Brahmashri Sena district head Ganesh Sharma, Madan Sharma, and Aditya Singh.
While Ranjan was the chief, Manish, reportedly, helped with the planning and their financial affairs. Bimlesh was their shooter and a key member of the extortion gang. While the trio hailed from Bihar, Aman was, reportedly, from Karawal Nagar in Delhi.
Ranjan had, reportedly, been openly challenging the police on social media and through audio messages. He had a bounty of Rs 25,000 on his head.
A recently recovered audio clip allegedly revealed that the Sigma Gang was planning something big ahead of the assembly elections in Bihar.
Bihar DGP Vinay Kumar said, "The gang was committing crimes almost every month. They were contract killers. They had named their gang 'Sigma and Company' and that itself indicates their intentions.
"Elections are about to be held in Bihar. So, we made a lot of effort to gather intel on this gang. Based on those intels, a team of Sitamarhi Police was camping in Delhi and was trying to locate them in coordination with Delhi Police. In this connection, they were being intercepted and it led to an encounter. All 4 were killed. A criminal from Delhi, Aman used to give them shelter there. There are other members of the gang too, information is being gathered about them. It was found that their plan is to disturb Sitamarhi Police and the entire district. It cannot be denied that they could have done something during the elections. They used to go out and plan and once the planning was done, they used to execute it...," Kumar added.
