Scamming and Frauds

Yesterday, when i was studying My phone rangs when i see it there was random number so, pickup the call and there was stranger person who saying that i win the lottery of 25 lakh rs, i was really shocked because i didn’t buy any lottery. So i cut the call then he message on my whatsapp some photos of cheque and some videos in which he was showing some money but i know he was froding me so i call my uncle who is in police and i told everything to them and i give the number of fraud person to my uncle.
