My wife had a consensual, adulterous s*xual encounter with someone sometime ago. Mental pressure over time was applied by the person and my wife succumbed in weakness, which was completely her fault. The incident was recorded with my wife's knowledge and the person has sent her a video of the same, perhaps with the intent of blackmailing her.
My first priority is to ensure the video is never released, and then to take action against this man. My personal issues with my wife will be handled thereafter.
Please advise the best way in our Indian scenario to ensure the video is never released, and what action should be taken against this man.
