The accused, Sombir alias Cheli, was arrested from PVC Market in Tigri in West Delhi yesterday by a police team, said Deputy Commissioner of Police (Special Cell) Sanjeev Kumar Yadav.
He had tried to fire at the police team in a bid to escape but was arrested after a scuffle with policemen.
"An Italian-made sophisticated pistol loaded with five live cartridges was recovered from his possession," the officer said.
Delhi Police had earlier announced a reward of Rs 50,000 on information leading to his arrest. Haryana Police too had announced a reward of Rs 25,000 on information leading to his arrest.
In Haryana, he, along with his associate Umesh, had fired bullets at the paternal uncle of Amit, a day after the latter's murder, said the DCP.
Umesh was also carrying a reward of Rs 75,000 on his arrest.
