An Arkansas day care teacher is charged with raping a 4-year-old girl during nap time. Police say the incident was caught on closed-circuit video, 4029tv.com reports.

Cesar Monarrez, 18, was a part-time employee at the Royal Children's Academy and had worked there for about three or four months. According to an arrest warrant, the alleged victim told authorities on Feb. 5 how Monarrez had touched her inappropriately.

The girl told police her privates were burning because "Bubba" touched her with a knife inside his pocket, 4029tv.com reports. Police identified Bubba as Monarrez, and investigators said video shows him pushing his hands beneath the girl's waistband while she was asleep.

Royal Children's Academy Director Howard Davis plans to send a letter to parents.

"What I would say to parents is that the owner of this company and myself have an utmost concern about their safety," Davis told 4029tv.com. "There wasn't anything that we saw or heard from any of our employees that would let us think for a second that there was something going on."
