A security guard's account at Lohagad Fort has shed light on the chilling events leading to Ketan Agarwal's death. He observed Ketan arriving with Siya Goyal, followed by Chetan Chaudhary, who appeared to deliberately conceal his identity. Police allege Siya and Chetan, her lover and co-conspirator, then pushed Ketan into a gorge, with Siya later fabricating a story of an accidental fall. The couple is now in custody.
