An Indonesian woman's bizarre claim that a gust of wind made her pregnant has prompted a police investigation.

The woman, identified as 25-year-old Siti Zainah, told local media that she got pregnant in a span of one hour. According to her, she found herself pregnant while sitting idle in her living room one afternoon.

"After afternoon prayers, I was lying face down on the floor when I suddenly felt wind enter my body through my vagina," she said.

Zainah reportedly felt pain in her stomach 15 minutes later, then her "baby bump" grew bigger. She delivered a healthy baby girl at a local clinic shortly after, Coconuts Media reported.

"After checks, the mother and baby are healthy and the birth was normal. The baby's gender is female and weighs 2.9 kilograms (6.4 pounds)," Eman Suleiman, the head of the clinic, told local media.

Local authorities and Suleiman visited the woman after her story spread like a wildfire. Suleiman believes that it is a case of cryptic pregnancy, where the mother does not feel her own pregnancy until she goes into labor.

Zainah separated from her husband four months prior to the incident and has a child with him. Local authorities have launched a probe and are planning to investigate all angles, including the woman's previous marriage.

"We want to clear up the confusing news about the woman's birth which many perceive to be unnatural. We want to avoid this incident from creating rumors among the public," a police officer said.

In a similar incident in Indonesia, a 19-year-old woman claimed that she had given birth despite being a virgin. Utje Ramadani reportedly got pregnant for only three hours before giving birth to the child.

Members of her family were adamant that the baby was magical and refused to allow authorities to see the child. The incident captured nationwide attention, with local non-profit organizations asking the authorities to launch a probe and debunk rumors surrounding the mysterious case.
