Superintendent of Police (SP) Amit Kumar confirmed that the injured criminal was identified as Shantanu Singh, who sustained bullet injuries during an exchange of fire between the police and the criminals. His accomplice was also arrested during the operation. The SP said Shantanu Singh was immediately admitted to a private clinic and later referred to Shri Krishna Medical College and Hospital (SKMCH), Muzaffarpur, due to his critical condition. Police recovered a pistol and three empty cartridges from the spot. According to police, Shantanu was involved in several serious crimes, including the murder of a priest in the Jafarpur area, looting of idols, and the murder of Jan Suraaj leader Ravi Singh, a resident of Bhorha village.
