In a joint operation involving the UPSTF and Gautam Buddha Nagar police, a sharpshooter, identified as Aniruddha, was arrested from the Bisrakh area last night.
A country-made pistol, three live cartridges, a motorcycle, a mobile phone and Rs 25,000 in cash were seized from Aniruddha, who hails from Muzaffarnagar, a spokesperson of the UPSTF said.
During interrogation, Aniruddha told police his uncle was a member of the Vicky Tyagi gang.
Three people were earlier this month arrested by the UPSTF in connection with the killing.
