California police are investigating reports that a number of second-grade students engaged in sexual activity while their teacher was present in the classroom.
Authorities were called to Markham Elementary School in Oakland where a second-grade teacher has been placed on administrative leave.
Police report that they have first-hand accounts from students that classmates engaged in oral sex and stripped off some of their clothes while class was in session.
The teacher, a man whose name has not been released, told officials that he did not see any of the alleged acts that took place last week.
He's been barred from campus until the investigation is completed.
A spokesman for the Oakland Unified School District released a statement on the situations saying,
"We believe if the reports are true, there was a serious lapse of judgment or lack of supervision in the classroom…We're investigating how could this have happened. It seems unthinkable to us, just the same way it does to the public."
