An emaciated newborn baby left all alone at home for several days after their mother died inside was rescued by Arizona police officers, who found the infant “clinging to life.”

Cops responded to the south Phoenix home last month after neighbors reported not seeing the mother for several days.

Bodycam video of the rescue shows officers calling out “hello?” from outside the apartment hoping to elicit a response, and breaking down the door when nobody responded.

The video then shows a tiny baby wrapped in blankets laying on a bed, where cops said the mother’s body was found. He puts the infant in a stroller before EMTs take over to render life-saving care, according to the footage.

“Inside the home, they discovered the mother had passed away and her baby was still alive, severely dehydrated and clinging to life,” police said in a press release Thursday.

“The baby was taken to the hospital in critical condition. We are happy to report, the infant’s condition has improved greatly, and they’re expected to survive.”

The name or gender of the child was not provided, and the mother was not identified — including her cause of death. Investigators described the infant as “visibly emaciated.”

In an interview with Arizona Family, cops said they had looked through an open window and spotted a motionless woman inside the home.

“The mother had passed away while the child was still on the bed still curled up where the mother had left them,” Phoenix Police spokesperson Sgt. Brian Bower said.

“It wasn’t learned until well after the fact from doctors and staff at the hospital that if the police officers didn’t immediately provide aid and didn’t immediately go into the apartment, the child may not have survived much longer,” he added. 

Bower chalked up the success of the tragedy-tinged rescue effort to the “smart, immediate actions of the officers as well as the neighbors seeing something unusual and calling in for help.”

The baby is now under the care of the Department of Child Safety, and police are still investigating how the mother died.
