According to their families, Ketan and Siya were engaged in February and the couple were set to get married later in the year.
The wedding venue had been booked and preparations were in full swing, their families said.
Ketan’s death hit the headlines last week after senior Pune police official Sandeep Gill announced the arrests and addressed a press conference, external.
The couple had gone to the fort when Siya reported his death, he said.
“But during our investigation, we came across some information and after talking to their friends and relatives, we grew suspicious.
“Ketan was an experienced trekker and it’s hard to believe that he would suddenly slip and die like that. His family also expressed some doubts and lodged a complaint,” he added.
Gill said when police started digging, they found that “Siya was in a relationship with Chetan and was unwilling to go through with the marriage with Ketan”.
He alleged that Siya and Chetan “conspired to kill Ketan by pushing him from the fort to make the murder look like an accident”.
Senior police inspector Dinesh Tayade later told the media that they cracked the case after spotting a man with a hoodie on the fort’s CCTV camera. That man, he alleged, had been identified as Chetan.
“When we checked the 18 June temperature, it was 33C that morning. During scrutiny of CCTV footage from the foothills, we noticed a person wearing a hoodie with his head covered and also wearing headphones.
“This raised suspicion because such clothing was unusual considering the weather conditions,” Tayade said, external.
