Two young women were killed by their father "in the name of honour" in Peshawar's Achar Kali area on September 20, police said on Saturday.
According to Bala Mani Deputy Superintendent of Police (DSP) Fazal Wahid, Abdul Gani killed his daughters — 20-year-old Shamim and 10-year-old Noreen — and confessed to the crime upon his arrest.
Amjad Gani, the accused's son, reported his crime to the police and lodged a first investigation report for his sisters' death, the DSP said.
According to Wahid, the police had to conduct several raids before the Abdul Ghani was apprehended from the Mosam Ghari area in Peshawar, two days after the murder.
According to the DSP, Abdul Ghani said killed his daughters because he was "ashamed at his daughters' conduct as they used to leave the house at all hours."
Last year, on October 6, a joint session of the Parliament unanimously approved anti-honour killing and anti-rape bills.
The legislation on honour killings will introduce strict punishment for the convicts making it tougher than the ordinary murder cases.
Under the new law relatives of the victim would only be able to pardon the killer if he is sentenced to capital punishment. However, the culprit would still face a mandatory life sentence of twelve-and-a-half years.
