The mystery over the source of the derogatory pamphlets targeting Aam Aadmi Party's east Delhi candidate Atishi seems to be deepening. The head of a housing colony in East Delhi's Krishna Nagar told NDTV that he had received the pamphlet by post on May 2, a week before Atishi's press conference on it. "I got the pamphlet at around 4 pm, and I had sent the screenshot of it to AAP workers here on the same day," one of the receivers of the pamphlet told NDTV, who did not want to be named.
