LOS ANGELES (CBS) — A woman has been charged with aggravated assault after allegedly grabbing a 4-month-old baby from his stroller and slamming him into a metal pole in front of his mother and aunt, according to police.

Natasha Hubbard, 36, was arrested July 21 after attacking the infant in the Toy District, near Skid Row. Police say Adriana Miranda was pushing her infant son, Alexander, who was belted into a stroller with her sister walking nearby.

Without warning, Hubbard unbelted the boy from the stroller and grabbed him by the leg. Witnesses told police she swung the child over her head and slammed him into a metal rail of a nearby truck.

“The mother and aunt fought off the woman and mom grabbed the baby,” Los Angeles police Lt. Paul Vernon said. “Hubbard attacked [Miranda], scratching and clawing her as she clutched Alexander in her arms.”

Miranda and her sister ran into a store for protection as Hubbard ran away, police said, but the owner of the store pushed the two women back out onto the street. Arriving officers were able to find Hubbard with the help of witnesses.

Hubbard told detectives at the police station that she tried to break off the baby’s arm so she could eat it.

“We’re so lucky Alexander was not more injured than the bruises and swelling he received,” Vernon said.

Miranda also sustained minor injuries in the attack.

Hubbard is being held on $55,000 bail and will be arraigned on Aug. 4.
