A newborn baby found abandoned in a plastic bag in the US state of Georgia is now "thriving", according to the local county sheriff's office.

On Wednesday, the Forsyth County Sheriff's Office (FCSO) released dramatic body camera video of the baby, who has been nicknamed "India", being rescued by police officers.

She was found on June 6, with the umbilical cord still attached and wrapped in a plastic bag, after residents heard her cries from a wooded area.

Police said she was putting on weight and healthy, and they had received numerous offers of help.

"We have been flooded with love for Baby India, including offers of foster or adoption and donations," the FCSO said on its Facebook page.

"We are so very thankful for the outpouring of love and support, and would not expect anything less from our amazing community.

"Please know that currently baby India is being very well taken care of by hospital staff and when she is well enough to leave the hospital the Division of Family and Children Services will be taking care to find a great foster for her."

Police released the vision hoping it would lead to more information on the whereabouts of the baby's mother.
