The Malad police have arrested four people, including a woman, for allegedly blackmailing a 37-year-old choreographer using an obscene video secretly recorded by one of his own students. The accused allegedly demanded Rs 9 lakh, threatening to make the clip viral.

According to police, the choreographer, who lives in Malad, received a WhatsApp call on December 15 from an unknown number. The caller claimed to possess his nude video and threatened to circulate it unless the money was paid. The clip was sent to him and later shared again from another number on Instagram.
