A newborn baby girl found wrapped in a towel in January on an east London street has been shown by DNA testing to be the full sibling of two other infants abandoned in the same part of the city. Despite an intensive police search, the parents of baby ‘Elsa’, and her siblings ‘Harry’ – a boy – and ‘Roman’ – a girl – who were discovered in 2017 and 2019 respectively, have not yet been found. The fact that three full siblings had been abandoned over a period of seven years could only be publicised following a legal battle by the BBC and PA Media, who argued that the family court judge overseeing the case should permit reporting of this highly unusual fact as a matter of significant public interest. The local authority and the baby girl’s court-appointed guardian opposed reporting.
