The tot, known as Baby Elsa, was discovered at the junction of Greenway and High Street South in East Ham by a dog walker at around 9.13pm on January 18 this year. 

DNA testing has now confirmed that two of Baby Elsa’s siblings were also abandoned in Newham.

The Met Police said officers carried out media appeals and carried out extensive door to door, witness appeal, forensic and CCTV enquiries after both children were found. 

After Baby Elsa was found an appeal was issued to find a woman seen wearing a large dark coat with a light coloured scarf or hood around her neck and had a rucksack on her back. 

Officers continue to believe she may hold important information about how Elsa came to be found. 

Newham Council continue to ensure all of the children's welfare, according to a Met Police spokesperson.
