The matter surfaced on October 18 last year, when a 25-year-old YouTuber approached the Santacruz police saying that her fans brought to her notice her obscene morphed photos online.
The investigation found that Jain had brought arsenic and thallium to Kajal, which she mixed in food, tea and juice and gave to her husband, Kamalkant. Kajal and Jain were arrested in December last year.
