OKLAHOMA CITY - Officials arrested an Oklahoma City Public Schools' employee for allegedly knowing about a child being sexually abused but not reporting it.

According to police reports, the girl called police and the Department of Human Services to report she had been sexually assaulted by Martha Espaillat's boyfriend at least four times.

Police say the girl told them Martha Espaillat, a bilingual specialist with Oklahoma City Public Schools, reportedly knew about the incidents, but did not report them.

The girl says the assaults happened on Christmas Day, New Years Day, and two other times. She says Espaillat told her she would talk to the man, but Espaillat ignored the accusations.

The girl also told police she's afraid her 6-year-old sister may also be a victim.

Oklahoma City public schools sent News 9 a statement on Monday saying the district is cooperating with police and conducting its own internal investigation.

Superintendent Karl Springer also says officials will take appropriate disciplinary action against the employee.

They did not tell us if Espaillat has direct contact with students.

No charges have been filed against the man involved at this point.
