Baby Elsa was found wrapped in a towel in a shopping bag near the junction of Greenway and High Street on January 18, 2024.
A year later, Metropolitan Police detectives are continuing their search for the parents – who they have “serious concerns” about.
To support this investigation, independent charity Crimestoppers are offering a reward of up to £20,000 for any information given to them anonymously.

Detective Inspector Jamie Humm from the Child Abuse Investigation Team said: “We have carried out extensive enquiries over the past year to try and locate Elsa’s parents.
“This has involved reviewing over 450 hours of CCTV and completing a full DNA structure of the mother.
“We have also worked with wider specialists who are of the view that the mum and possibly also the father have been residing in the Plaistow or East Ham area over the past six years.
“We have serious concerns for the well-being of the parents, especially the mother and are continuing to work closely with Newham Council and appeal for the public’s help for information.”
Elsa was thankfully uninjured when she was found by a dog walker at around 9.13pm on January 18, 2024, although she was taken to the hospital as a precaution.
She has since been placed into the appropriate care, and was named by the authorities.
Later enquiries by the Met’s Child Abuse Investigation Team revealed that Elsa was biologically related to two other babies, who had also been abandoned in the area in 2017 and 2019.
Det Insp Humm said: “I believe that someone in the area will have been aware of the mother’s pregnancies and that within the community there may be have been concerns for this mother’s welfare.
“I share these concerns with you so if you have any information, no matter how small it may seem, please contact us.
“The three babies in this investigation are thankfully healthy and well, and we are continuing momentum behind this investigation to identify the parents.”
