Ahmedabad, Feb 15 (PTI): An NRI couple was booked for allegedly murdering a boy, whom they adopted in 2015, so as to pocket the insurance amount of Rs 1.20 crore which they had taken as cover for the latter's life, police said.

Police lodged an FIR against Arti Loknath and her husband Kanwaljitsinh Raijada, currently living in London, for allegedly being part of the conspiracy to murder Gopal (13), said Keshod police inspector Ashok Tilva.

"Arti and Kanwaljitsinh conspired with one Nitish Mund to adopt Gopal (13), get him insured and then kill him so that they could get insurance money. Nitish, who also lived in London before shifting here after his visa expired, had planned along with the couple since 2015 to kill Gopal," Tilva said.

The NRI couple's role was revealed after police arrested Nitish yesterday in connection with the murder.

The boy had died at a Rajkot hospital yesterday, days after he was attacked with knief by unknown accused riding two motorcycles on the night of February 8 in Keshod in Junagadh district.

Gopal was returning from Rajkot to his home town Maliya along with Nitish, Harsukh Patel, and one Mahadev, Tilva said.

He was living with Nitish who planned the attack by hiring two assailants for Rs 5 lakh each, Tilva said.

"Hired assailants attacked Gopal and Harsukh Patel after they came out of a vehicle at a pre-decided place at Keshod. We have initiated process to arrest the NRI couple who are at present in UK," Talvia said.
