US police find baby abandoned inside plastic bag

Footage from a police officer's body camera has captured the moment a baby was found alive abandoned in a field.

The baby, temporarily named India, was found wrapped in a yellow plastic bag in Forsyth County, Georgia on at around 10pm on June 6, ABC reports.

Investigators still have no idea of the baby's actual identity or who her parents are. She was hours old when she was found.

The video shows officers tearing open the plastic bag India is trapped in and wrapping her in a blanket. 

"She's a sweetheart," one officer said.

The Forsyth County Sheriff's Office said in a statement it is "aggressively" pursuing any leads to try and find whoever abandoned the baby.

It also reminded people the state of Georgia has a safe haven law.

"This law allows a child's mother to leave her baby, up to 30 days old, with an employee of any medical facility including any hospital, institutional infirmary, health centre or birthing center in Georgia without prosecution."

India is currently in the care of the Georgia Department of Family and Children Services. The Forsyth County Sheriff's Office said she is doing well.
