OKLAHOMA COUNTY, Oklahoma - Oklahoma County Sheriff's deputies arrest a teacher accused of having a sexual relationship with an underage student.

Eric Harris, 37, faces complaints of first degree rape by instrumentation, indecent or lewd acts with a child under 16, two counts of forcible oral sodomy and possession of obscene materials.

Harris teaches at the Millwood Freshman Academy in Oklahoma City and is also the school's boys basketball coach. The arrest was announced at a news conference on May 23.

According to the sheriff's department, administrative staff with Millwood Public Schools notified deputies of the alleged abuse after a student reported an inappropriate relationship between Harris and another 15-year old female student. Deputies interviewed Harris on May 23 and arrested him.

"Harris has admitted that he committed the crimes over a six month period with the most recent incident happening within the past few weeks," said Sheriff John Whetsel with the Oklahoma County Sheriff's Office.

Millwood Public Schools educates students at its Arts Academy, high school and school for students in pre-kindergarten through eighth grade.

"This is a most unfortunate situation for all persons involved," said Millwood Public Schools Superintendent Dr. Gloria Griffin. "While this is an isolated incident that occurred, we pledge to continue to monitor your children's safety while they are in our care."

The married teacher and coach is being held in the Oklahoma County Detention Center. Bond has not yet been set in the case.
