HOUSTON -

A Yates High School teacher has been arrested, accused of having a sexual relationship with a female student.

De Sergio Geterus Parrish is facing one count of improper relationship with a student and two counts of sexual assault of a child. Investigators say Parrish, a history teacher, and a 16-year-old girl had sex on more than one occasion.

According to court documents, the girl told investigators that a sexual relationship between her and Parrish began when he gave her a ride home during her tenth grade year in January 2012. She said Parrish followed her into her bedroom, where the two had sex.

The girl also said the two had sex several times at her home and his home.

During a police interview, detectives said Parrish denied the allegations, but later admitted to sexual acts with the girl.

Investigators said Parrish, 31, told them that he realized his actions were wrong and that he had made a mistake.
