HOUSTON - A high school teacher has been charged and arrested following allegations of inappropriate contact with a special needs student.

According to HISD, 54-year-old Albert Lee Randall has been charged with having an improper relationship between an educator and student. The district says Randall was a teacher at Wisdom High School.

According to the charging document, a witness told police that he saw Randall touch an adult, non-verbal, special needs student in an inappropriate way. The witness told authorities about what he'd seen.

Police say that Randall later admitted that he used his hand to touch the student for about "fifteen minutes, maybe longer". The document also states that Randall told police that he did not have an explanation for why he did what he did, but that he knew it was wrong.

HISD says that allegations were first reported to school officials in February, at which time Randall was removed from campus and an investigation began. Police presented their findings to the Harris County District Attorney's Office, which accepted criminal charges.
