Lahore incident
Earlier this month, unidentified men gang-raped a girl and left her on a road in an unconscious condition in Lahore.
As per details, the girl was found in an unconscious state on the road adjacent to Jheddo village in Kahna. Upon receiving information from residents, police reached the spot and shifted the victim to a hospital.
In her statement to the police, the victim said that two men raped her, and after abusing her, they left her on the road in an unconscious condition.
The police had said that further investigation is underway to ascertain the facts.
Khairpur acquittal
Last month, a former Khairpur teacher was acquitted of raping his students, causing an online backlash.
The convict, Sarang Shar was acquitted by a sessions judge of the district who ‘scrutinised’ the evidence and police reports before reaching the said conclusion.
Shar – who offered private tuition – was arrested in 2020 after videos and pictures of him molesting the children went viral on social media.
