It comes after the brutal killing of Zainab Ansari (pictured) - whose body was left in a rubbish dump in Kasur, East Pakistan

Pakistan's senate has been asked to pass a bill to re-introduce public hanging for people who rape or kidnap children under the age of 14.

It comes after the brutal killing of Zainab Ansari - whose body was left in a rubbish dump in Kasur, East Pakistan, after she was snatched while on her way to a class - unleashed a wave of revulsion around the country.

Chairman of the Standing Committee on the Interior Rehman Malik said an amendment to an existing law had already been approved by his committee and should be put before the senate.

According to Dawn News, the amendment to Section 364-A of the Pakistan Penal Code Act 1860 declares that the punishment for kidnapping or raping a child is to be public execution.

The section currently reads: 'Whoever kidnaps or abducts any person under [the age of fourteen] in order that such person may be murdered or subjected to grievous hurt... or to the lust of any person shall be punished with death.'

The amendment seeks to add 'by hanging publicly' after the word 'death', according to Malik.

Malik explained that an example should be made out of Zainab's murderer.

A man, named as Imran Ali, has been arrested after his DNA matched samples found on her body, according to police sources. He has since confessed to the killing, officials say.

Today he was brought to a court in Lahore.

Yesterday morning, local reports said furious residents had surrounded his house. Police were on the scene and have urged people to remain calm.

The suspect is said to be a resident of the same area where Zainab's house is located, Dawn News reported.

Zainab, six, was snatched in early January as she walked to a Koran class.

CCTV footage showed her being led away by a suspect five days before she was found raped and strangled on a rubbish pile about a mile from her home in Kasur, east Pakistan.

Her parents were away on pilgrimage in Saudi Arabia, and the girl and her two sisters and brother were watched over by her aunts and uncles who all live in the same house in an impoverished neighborhood of narrow lanes on the outskirts of the city.

A police district official told Al Jazeera: 'The suspect's name is Imran and he lives in the same [area] where Zainab lived.

'He was arrested before, but was released as we did not have evidence. After that he shaved his beard off so that no one could recognise him.'

The official said that the suspect has confessed.

The horror of Zainab's killing was brought home for Pakistanis by a photo of her that was widely shared on social media, showing the smiling girl in her favorite bright pink coat, with a pink barrette holding back her hair.

TV channels aired the photo alongside pictures of her lifeless body abandoned on a heap of garbage in her home city of Kasur.

There were 4,139 cases of child sexual abuse reported in Pakistan in 2016, according to Sahil, an organization documenting child abuse in the country.

It collects its figures by tracking reports in Pakistani media. But most cases go unreported, said Sahil's executive director, Munizae Bano.

Across Pakistan, thousands protested, condemning police inaction and blaming the government for failing to protect children.

Kasur is a congested district of around 2.5 million people in eastern Pakistan, near the border with India.

The city of Kasur is surrounded by brick kilns and tanneries and has hundreds of small factories making shoes and embroideries, all of which employ children - making them vulnerable to abuse.

In 2015, an extensive child pornography ring was uncovered in the city; it had been flourishing for nearly a decade and involved nearly 250 children, some of whom were forced at gunpoint to have sex.
