The 25-year-old was taken into custody on Monday after the baby’s mother saw her in the Edendale Mall, Captain Thulani Zwane said.
The two-month-old baby boy was reunited with the mother and was in good health.
The baby was snatched on April 15 at the home affairs department while his mother was filling in documents for a birth certificate. The woman allegedly disappeared after offering to hold the boy for the mother.
She would appear in the Pietermaritzburg Magistrate’s Court on Wednesday.
