Since yesterday’s appeal detectives have received information from the public and are following up lines of enquiry today.
Officers continue to appeal for vital information to help uncover how the newborn baby came to be in the waste treatment plant on Valley Road Bradford, where her body was discovered at around 2.30am on Thursday.
Following a post mortem yesterday, it appears the girl was white, but a cause of death has not as yet been ascertained.
It is however believed the youngster was unlikely to have been born in a hospital and may have died two to three days before her body was discovered.
Enquiries have revealed some 97 loads of waste were delivered to the Valley Road unit on Wednesday, 51 of which were from Bradford and the remainder were from elsewhere in West Yorkshire.
This raises the possibility the youngster may be from an area of West Yorkshire other than Leeds and Bradford.
Detective Superintendent Sukhbir Singh who is leading the enquiry, said: “I thank members of the public who have contacted us so far. Our focus continues to be to identify this baby’s mother and I would urge her friends, relatives and neighbours to contact West Yorkshire Police.
“Somebody in West Yorkshire must know who the mother of this child is and I would ask them to provide the key piece information we need to find her.
“We remain greatly concerned for the mother’s condition and welfare and want to ensure she gets the medical attention she deserves.”
Anyone who has information should DS Ian Lawrie at the Homicide and Major Enquiries Team on 0845 60 60 606.
