In a letter to the Union Home Secretary and Jammu and Kashmir Home Secretary on September 18, Iltija has sought the details.
She said her mother has been detained since the evening of August 5. "I was able to meet her in the last week a few times in private, following an order of the Supreme Court enabling me to do so on September 5."
"During the period of her detention, she has had no access to newspapers, and has not had any political briefing from any member of her party or staff thus far. She has only been able to meet the members of her immediate family, including myself.
"In my meetings with her, my mother expressed concern at the number of detentions and arrests (and in particular the reports of detention of children) that have taken place in the state" in the aftermath of abrogation of Article 370 and 35A and bifurcation of the state into two Union Territories.
"I am reiterating that I am not a politician or a person with political affiliations. I am doing this on behalf of my mother, who is a politician and a president of a registered political party," writes Iltija, who announced on Twitter that she has taken over her mother's Twitter handle.
She sought details of the number of residents who were detained/arrested or placed under house arrest on or after August 5, including the name of the district and police station and their current status.
She sought the number of minors, under 18 years, children between 12-15, children in age group under 12, and women who have been detained/arrested or placed under house arrest on or after Aug 5.
She also sought details of those who have been shifted to jails and detention centres out of the state, on any deaths of detenues in the state after August 5, the number of those detained under the Public Safety Act, and on the number of those who have not had any meeting with relatives or friends so far.
Iltija also asked the number of such detenues for whom habeas corpus petitions have been filed or notices issued in the state high court, as well as the number of detenues who have been released following orders of the high court.
She also sought details of the number of districts or places that were still under prohibitory orders, as well as a list of such places along with the date of the prohibitory order issued.
Separately, in a media event in Mumbai, Iltija attacked the Narendra Modi government for holding her mother and other political leaders under preventive detention in Jammu and Kashmir.
She also said that it is wrong to assume that every Kashmiri is a potential stone-pelter or a terrorist.
"Every Kashmiri is not a stone-pelter. We are as aspirational as others," she said.
Iltija also challenged the assertion that "political dynasties" had destroyed Kashmir over the years.
