A couple have been arrested on suspicion of attempting to abduct a premature baby.
A 31-year-old man and a 26-year-old woman are said to have visited Great Ormond Street Hospital on Monday afternoon (March 6).
The pair told staff at the hospital that they had a baby at 21 weeks at the Royal London Hospital in Whitechapel on March 1, according to The Telegraph.
Claiming they had come to collect their baby from the neo-natal unit, they showed staff a picture of a baby in an incubator, which is believed to have been printed from the internet.
No records were found for a premature baby born at the Whitechapel hospital on March 1 so hospital staff contacted police about the incident.
Inspector Paul Clarke from the Metropolitan Police said it "could have been a very frightening and harrowing incident" if the couple had managed to take a baby.
Both have been released on bail, but are not allowed to enter any hospital unless they have a medical emergency.
