India, Aug. 4 -- A 28-year-old man from Uttar Pradesh was arrested on Saturday for allegedly stalking, blackmailing, and threatening to circulate private photographs and videos of his 20-year-old relative, police said on Sunday.

The accused, police said, had been allegedly pressuring the woman to continue their relationship and fulfil sexual demands by threatening to make her personal content public.

The case came to light after the victim's 19-year-old brother lodged a complaint with the Cyber Police Station of northwest Delhi on July 25, said deputy commissioner of police (northwest) Bhisham Singh. The complaint alleged that a relative from Bulandshahr had sent him sexually explicit images and videos of his sister on Instagram.
