Khan made his comments while demanding 'exemplary sentences' for the woman's rapists, saying he would sentence them to be hanged at the site of the attack, but admitted that hanging them might lead to Pakistan being punished by the EU, so it might be better to chemically castrate them instead. 

Speaking on Pakistani TV on Monday September 14, Khan said: 'What I think is that there should be chemical castration, I have read it is happening in many countries.

'The way murder is graded: First-, second- and third-degree. This should also be graded, and for first-degree (sex crimes) there should be castration.'

According to Mail Online, the attack took place in the early hours of Thursday last week after the woman's car broke down on a highway near Lahore when she ran out of petrol.

While still in her car, she locked the doors and called for assistance, but a group of men smashed her window and dragged her out before they attacked her. 

After the rape ordeal was over, the woman was also robbed.

Police arrested 15 men last week but said none of them were involved in the rape. Officers have since named two primary suspects as Shafqat Ali and Abid Malhi in the case. 

Shafqat was taken into custody on Monday, with police saying his DNA matched samples found at the scene, and he has confessed to the crime.
