Overview

• CBI ASI Virendra Singh was attacked with an iron-tipped arrow outside the CBI office in Hazratganj, Lucknow, on May 23, 2025, sustaining serious injuries but is now in stable condition.
• The assailant, Dinesh Murmu, a 55-year-old from Bihar's Munger district, was apprehended on-site and faces charges of voluntarily causing hurt and attempt to murder.
• Investigators suspect the attack stems from a personal grudge tied to Murmu's dismissal from Indian Railways following a 1993 CBI-led probe into train bombings.
• Murmu reportedly spent months preparing for the attack, crafting a handmade bow and sharpened metal arrow for the assault, and may have conducted surveillance beforehand.
• Authorities are reviewing security protocols at the CBI office, as well as any prior threats or surveillance targeting Singh, as part of their ongoing investigation.
