A five-year-old girl was raped and killed in Larkana's Naudero town on Monday, police and medical examiners said on Tuesday.
The suspect allegedly lured the minor girl to a deserted area near the town's railway station and strangled her to death after raping her, and disposed off her body in a pool of water, the area police said.
The girl's body was taken to a taluka hospital in Naudero where Dr Ghazanfar Khokhar and a lady doctor Dr Salma Katpar conducted a postmortem examination on her. An initial checkup confirmed both the sexual assault and strangulation of the minor girl.
The suspect, who was arrested during police raids in the area, confessed to the crime during interrogation, Station House Officer Sartaj Jagirani told local journalists.
He said that both the victim and the accused were residents of the Ghurghal Shah locality of the town, adding that a thorough probe into the assault was underway.
Police registered a case against the suspect on the complaint of the girl's father under sections 302 and 376 of the Pakistan Penal Code and sections six and seven of the Anti-Terrorism Act.
The girl's body was handed over to her parents for burial following the autopsy.
