blackmail to expose a girl

sir,
first of all i am thankful to all the great lawyers of my country who are always there with there best suggestions.
recently i came across a situation where my frnd shared a situation where he wander to commit a murder of commit suicide.now i have suggested him that he does not need to do the both the brilliant minds are always with us to show the most perfect pass
sir the situation is very clear elder sister of my frnd had a frnd(male) whom she met during a marriage ceremony now they just like frnds clicked few pictures

as per my frnd the photos were normal not in any negative pose.but her sister is afraid that if the boy shared them on social media it would be a shameful moment for thier parents in the village and it might make a doubt in her husbands mind

according to him the boy had the photos on gmail..not easily but it could be achieved and deleted but it could be then a worst step if he had the pictures at any other place

my frnd came to know about the pictures from a frnd of the boy who had seen many pictures of whom with many other girls hence he cane to know that he had already blackmailed many,after knowing about the photos he in a aggresive manner asked his sister.his sister told the whole story even though that she gave the whole money she had by the boy is still blackmailing her and she dont want her married life to be destroyed


overall i have suggest him to send a mail to the cyber crime mentioning the situation and describing the consequences therefore asking them to take a step against him secretly although all the proves would be attached .....as per my knowledge such people should be behind the bars such people dont deserve to be in our society

sir is there any other suggestions please suggest
