The gunfight broke out on the intervening night of Sunday and Monday, Additional Director General (ADG) of UP Special Task Force (STF) Amitabh Yash said in a statement.
The exchange of fire took place in the Simbhaoli area of Hapur district, involving the Noida unit of the STF of the Uttar Pradesh Police, along with Bihar Police and Hapur police.
During the encounter, the gangster sustained a gunshot injury to his chest and was rushed to a hospital, where he succumbed to injuries, he said.
According to ADG Yash, a significant quantity of firearms, cartridges, and other items were seized.
Yadav was the main accused in the abduction and murder of Vikash Kumar alias Rakesh Kadam, the block president of the Hindustani Awam Morcha (HAM party) and a social worker, in Begusarai district, the STF said.
On May 24, 2025, Yadav, with the help of his gang, kidnapped Kadam from the Sahebpur Kamal area and took him to the riverine 'diara' region where he was killed and buried under sand to conceal the body, the STF added.
