After exchanging phone numbers, she offered the man a lucrative investment plan (Representational)

A 72-year-old man was allegedly duped of Rs 70 lakh by an unidentified woman on the pretext of offering him a business investment plan, police said on Saturday.

The woman befriended the complainant-- Satyavrat Sharma, a former school teacher, through Facebook and got the money deposited in different bank accounts, they said.

Sharma, a resident of Alwar, lodged a police complaint on Friday, claiming that the woman was based in London and approached him through social media.

After exchanging phone numbers, she offered him a lucrative investment plan following which he deposited the money in different back accounts provided by her, they said.

A case has been registered at Aravali Vihar Police Station, said Deepak Kumar, DSP Alwar South.

It seems to be a matter of spoofing as the victim received phone calls from numbers registered at different locations including Dubai and London.
