MERIDIAN - A teacher at Mountain View High School was arrested Tuesday, accused of having sex with a student.

Meridian police arrested 26-year-old Rebecca E. Mason-Cales of Boise, who's being held in the Ada County Jail on six felony counts of sexual battery of a minor child.

Police said the West Ada School District received an anonymous email on Tuesday about a possible sexual relationship between Mason-Cales and a student. The district immediately contacted Meridian police, who launched an investigation.

Police said they quickly gathered evidence of a sexual relationship between Mason-Cales and a 17-year-old male student. They said the relationship started in August 2017.

At this time, police don't believe there are any other victims.
