A claim that South African woman Gosiame Sithole gave birth to 10 babies earlier this month is not true, an official inquiry has found.
No hospitals in Gauteng province have a record of decuplets being born, the provincial government says.
Medical tests show that Ms Sithole had not even been pregnant recently, it said.
The 37-year-old is now being held under the mental health act for observation and will be provided with support.
The statement did not elaborate on the reasons behind the fabrication of the story.
It went on to allege that Ms Sithole delivered the children on 7 June at Steve Biko Academic Hospital (SBAH) in the capital, Pretoria, saying staff were ill prepared.
It accused the hospital and the provincial health authorities of trying to cover up medical negligence.
“These allegations are false, unsubstantiated and only serve to tarnish the good reputation of Steve Biko Academic Hospital and the Gauteng Provincial Government,” the latest statement said.
Legal action would be taken against the editor-in-chief of Pretoria News, Piet Rampedi, and IOL, it said.
Where did the story come from?
Ms Sithole, who has six-year-old twins, and her partner Teboho Tsotetsi lived in Thembisa, a township with many working-class residents in Gauteng province near Johannesburg.
According to IOL, they attended the same church as Rampedi where he was introduced to them in December. In May it is alleged he interviewed the couple who said they were expecting eight babies – a photoshoot shows Ms Sithole looking heavily pregnant.
The birth of a surprise 10 babies was announced by Pretoria News on 8 June quoting Mr Tsotetsi as the source. He later said he had received text messages from his partner telling him about it, adding he was not allowed at the hospital because of coronavirus restrictions.
Rampedi also relied on WhatsApp messages – and did not get independent confirmation from the hospital of the story.
Their local mayor then confirmed the births – which is when other outlets, including the BBC, published the story – but a government spokesman later said the politician only had the family’s word and no-one had yet seen the babies.
Donations began flooding in for the couple and their reported babies, dubbed the “Thembisa 10”, including 1m rand ($70,000; £50,000) from IOL chairman Iqbal Survé.
But the story drew suspicion after Pretoria News initially failed to disclose the hospital where the babies were born and a series of hospitals in Gauteng came out to deny their involvement.
Ten days after the alleged births, IOL made the accusations against SBAH.
The couple seemed to fall out in the aftermath with Mr Tsotetsi reporting her missing and asking people to stop donations a week later, while Ms Sithole accused him of wanting to benefit financially from the babies, the Pretoria News reported.
Meanwhile social workers managed to track down Ms Sithole and she was admitted to hospital for tests last Friday, the Gauteng provincial authorities say.
A leaked memo seen by News24 alleges that Rampedi has recently apologised to IOL for “the reputational damage” the story has caused the group, saying he should have treated it more like an investigative piece rather than a “feel-good story
