A sessions court in the provincial capital on Tuesday approved a six-day physical remand of the motorway gang-rape suspect, Shafqat Ali, when he presented today after his arrest a day prior.

Shafqat — who was arrested from Dibalpur and confessed to committing the crime alongside key suspect, Abdi Ali, who is still at large — was booked in a case registered on behalf of the gang-rape survivor's relative, police said.

Police also added that apart from Sections 376 and 392, a terrorism clause was also included in the first information report (FIR) filed at a Lahore police station.

On Monday, Punjab Chief Minister Usman Buzdar had confirmed the arrest of one of the two suspects in the gang-rape case, stating on Twitter that "his DNA has matched, and he has confessed to the crime.

"Our entire team is constantly trying to arrest the accused Abid Ali, whose arrest is expected soon, God willing," Buzdar had added.

Shafqat is the second suspected rapist apart from Abid Ali, sources had informed a day earlier, and that Waqarul Hassan Shah and Abbas were not suspects anymore. They added that the arrested man was a habitual offender and had been involved in crimes in the past as well.

They said Waqar claimed that Abid had links to Shafqat and his brother-in-law, Abbas, the latter of whom has been detained. Shafqat was then arrested from Dipalpur after being traced through his phone SIM card.

The horrendous crime has sparked anger and countrywide protests calling for public hanging of the rapists.

Earlier, On September 14,  Prime Minister Imran Khan in an interview with a private channel late Monday had said there should be fearsome punishments for the sex crimes.

"There should be public hangings but unfortunately when I had a discussion about it I was told that there is no international acceptance for it, and the European Union has given us GSP status for trade and this could affect it", he had said.

However, he had said there should be "chemical castration", if not public hanging, to stop the repeat of sex crimes.
