Carroll Middle School teacher Angela Barnes, 45, is facing charges of alleged sexual assault of a child and having an improper relationship with a former student, police say.
Barnes was arrested Monday after authorities say they discovered she had been in a romantic relationship with a 15-year-old boy in June and July. However, the relationship had since ended.
According to Keller PD, the investigation began after detectives were given a tip late September that Barnes was in a relationship with a former student.
It's unclear whether she has acquired legal representation or is still in custody at this time.
