"The Chief Electoral Officer has been asked to provide us with CDs of the controversial statements. The district election officers have also been asked to submit detailed reports on the remarks at the earliest," EC sources told PTI here.
While Yadav attracted EC's attention for his reported remarks that he will "destroy" BJP's Amit Shah, details on Azam Khan's 'Kargil' remarks have also been sought.
Union minister Ajit Singh's statement that to prevent communalisation, he could even throw BJP's Prime Ministerial candidate Narendra Modi into sea has also attracted EC's attention.
The poll body has also received complaints with regard to the remarks.
Addressing the media in Lucknow yesterday, Yadav had said that it is unfortunate that people like Amit Shah are not behind bars.
"People like him are making divisive speeches. We will fight BJP like we have and we will destroy Amit Shah," the Samajwadi Party chief had said.
EC has taken cognisance of the "destroy Amit Shah remark", the Commission sources said.
Shah, a close aide of Modi, has received an Election Commission notice for a series of hate speeches in Muzaffarnagar in UP.
The sources said details of senior UP minister Azam Khan's 'Kargil' remarks have also been sought.
