However, the main suspect seen walking away with the girl is still at large. "I am a mother", she said, at the start of the show. CCTV footage showing her with a stranger near Peerowala Road has since gone viral.
A petition has been filed in the session court for the registration of a murder case against the Punjab chief minister Shehbaz Sharif and law minister Rana Sana Ullah in respect of two persons killed during police firing on a protest rally staged against the murder of 7-year-old Zainab in Kasur.
Zainab's death comes less than three years after a scandal in Kasur when at least 280 children were filmed being sexually abused by a gang of 25 men, who blackmailed their parents by threatening to leak the videos.
"They had thrown stones on the buildings of the government hospital, police and deputy commissioner's office... security is being deployed and trying to control the situation", he said.
The outrage has spilled over in Kasur after the body of the child was found in a garbage heap on Tuesday, where she is believed to have been dumped after being raped and murdered.
"We will not bury her until we get justice", he asserted at the time. "In the previous incidents, the forensic evidence also determines it and the modus operandi of carrying out such acts also determines it", spokesperson of Punjab province - where Kasur is located - Malik Muhammad Ahmad Khan said. Protests and demonstrations filled the streets of Pakistan with people demanding justice for the girl.
A number of police officials have been transferred out of the region for failing to investigate complaints of missing children since 2015, when authorities uncovered what they said was a paedophile ring linked to a prominent local family.
Senate Chairman Raza Rabbani suggested introducing appropriate legislation and stricter legal implementation in order to prevent such incidents in the future.
Laws for the protection of children must be made in line with worldwide laws, he said.
