Police allege Pune businessman Ketan Agarwal's fiancée Siya Goyal and her boyfriend Chetan Choudhary extensively planned his murder, including searching online for ways to kill someone.
Investigators said the duo exchanged over 2,000 phone calls in six months and met before allegedly pushing Agarwal off Lohagad Fort.
Both have been arrested and booked for murder and criminal conspiracy under the Bharatiya Nyaya Sanhita.
