LOS ANGELES – There are two LAPD officers being praised for efforts Saturday in reviving an unresponsive 3-week-old baby. According to authorities, the infant’s father slammed the boy on the ground.

Police said one of the responders, identified as Officer Alex Frazier, used modified chest compressions for some time to get the boy breathing again, according to NBC Los Angeles.

Authorities had received multiple 911 calls of possible domestic and child abuse occurring at the Westlake apartment, according to the station.

The mother told arriving officers that the boy’s father had been holding him like a football while hitting her, according to KTLA. The mother reportedly told police she was pleading for him to give her the child but he slammed the infant on the ground.

“It’s just unbelievable someone could hurt a child,” said neighbor Leonardo Artiga.

Someone had called police because they were scared when they heard yelling coming from inside the apartment, just feet away from the front door. Police say that after being slammed to the ground, the baby stopped breathing and that’s when the woman ran outside screaming for help.

When officers arrived, they found the child’s mother had suffered scratches during a fight with the father.

She was holding the little baby in her arms. Both responding officers are fathers of young children. As a result, the scene and the sight of the newborn who was nearly lifeless in his mother’s arms struck them.

“To see him like that, so defenseless, so vulnerable, it’s tough to see,” said Officer Ivan Ibarra.

Ibarra’s partner, Officer Frazier, quickly began chest compressions on the infant. After about a minute of the compressions, the child began breathing again.

“It was amazing, just to see the baby’s lip move. To see him move his neck, a facial expression, it let me know there was hope,” Frazier said. “I’ve seen a lot on this job, but to see a baby that wasn’t moving, lifeless — it was pretty scary.”

The officers actions represent tasks performed by cops everywhere, yet they go widely unreported. To see life returned to a baby after not breathing is amazing.

“Eventually, he just kinda rolled his head a little bit, and let us know he was in there a little bit more,” Frazier said. “So I just continued until the paramedics got there.”

The father was arrested at the scene and booked on a charge of child abuse, LAPD officials said. The mother and baby were taken to a nearby hospital for treatment.

The mother received minor injuries to the face during the fight and the baby was slightly bruised, police said.

Meanwhile, neighbors were grateful for the officer’s actions. “There’s still a lot of kindhearted people and they’re trying to serve and protect this country and this place,” Artiga said.

The identity of the father was not immediately released.

“It hits home, especially when you have small children,” Ibarra said. “My son’s only 10 months old.”

Frazier said the experience made him think of his own children, too.

“I went home immediately and kissed my kids,” Frazier said. “I’m a parent. My kids are my everything.”
