Ketan Agarwal's death was initially believed to be a tragic trekking accident at Lohagad Fort near Pune last week, but it soon turned into a murder investigation after the police found a suspicious CCTV footage - showing a man wearing a hoodie in Maharashtra's scorching heat during the hike. According to the police, the CCTV showed Ketan and his fiancee Siya Goyal walking together at the fort. Another man, now identified as Chetan Choudhary - Siya's lover - was following them from a close distance of around 20 to 30 feet. He was seen wearing shorts and a hoodie that covered his face. He was also wearing a headset over the hoodie
