A woman has been raped in the complex containing the mausoleum of Pakistan's founder in Karachi city, police say.
The newly-wed victim was visiting the mausoleum
The victim, who has not been identified, went missing two days ago on a visit to the mausoleum of Pakistan's founder Mohammad Ali Jinnah.
She was visiting the city with her husband from the central province of Punjab, police say.
Karachi, Pakistan's only port and its largest city, has a high rate of crime, including kidnappings and rape.
"The rape took place in a room in the museum within the mausoleum compound," Superintendent of Police, Niaz Khoso, told the BBC.
"After she recorded her statement, we searched the premises."
"We found pieces of her clothing, bits of hair and other pieces of evidence," he said.
The woman recorded her statement with the police after a medical examination at a local hospital.
According to her statement and that of her husband and family members, she arrived in Karachi from the central Pakistani town of Lodhran three days ago.
The newly-wed 19-year-old victim said she was kidnapped at gunpoint by two men from the gate of the mausoleum on 15 March.
She told police she was drugged and then raped by her kidnappers and other men who later joined them.
In the meantime, her family reported her as missing to the local police.
On 17 March, the victim was found in a drugged state by paramilitary personnel on guard duty at the mausoleum.
She was handed over to the police, who got in touch with her family.
