CINCINNATI -- Police said an 11-year-old boy threw a 1-year-old boy out of a third-floor window over the weekend, according to WLWT-TV in Cincinnati.

Police had responded to a report that the child had fallen out of a stairwell window in an apartment building in Cincinnati. But police quickly became suspicious of the account and started a criminal investigation.

The 11-year-old, described as a family acquaintance, was charged Monday with felonious assault and has been issued a citation to appear in juvenile court.

The baby, Levontay Clark, landed in soft mud and suffered only minor injuries, police said. He was playing and appeared OK beside his mother when she talked Monday with WLWT-TV.

The baby's mother, Lawanda Clark, said the 11-year-old's mother was supposed to be caring for the baby.

The 11-year-old occasionally helped baby-sit, the baby's mother said.

"He's holding my baby, changing his Pampers, giving him juice in his bottle, and now, this is the 11-year-old that pushed my baby out the window. I was kind off messed up in the head," Clark said.

Police had responded to a call about 5 a.m. Sunday that the child had fallen out of a stairwell window in an apartment building in Cincinnati.

But police quickly became suspicious of the account and started a criminal investigation.

Police questioned how the 1-year-old managed to raise himself to the stairwell window and how he managed to get in the stairwell in the first place.

"It seems odd," Lt. Chris Ruehmer said during the investigation. "The window in the stairwell is a good reach."

When investigators arrived on the scene, the child's mother wasn't there and adults in the apartment were asleep.

Police said the baby fell on the one spot in the yard that wasn't covered by debris or trash.

The child suffered multiple scratches to his face and was treated at Children's Hospital.
