PM Modi on Wednesday attacked AAP chief Arvind Kejriwal over his remarks that "poison" is being mixed in the Yamuna, saying that fearing their defeat in the Delhi polls, "AAP-da people" have turned desperate, PTI reported.

Speaking in a public meeting in New Delhi's Kartar Nagar in the run-up to the February 5 Delhi assembly polls, he also linked AAP leaders to serial killer Charles Sobhraj, who gained notoriety for duping people.
