30-year-old Justin Wallin, a band teacher at Chino Hills High School in Chino Hills, California has been arrested for allegedly having sex with a 16-year-old female student.

The victim reported to police that she was sexually involved with the man while he was her band teacher after her parents discovered sexually explicit text messages from Wallin on her phone.

After reviewing their phone bill police discovered over 8,000 text messages from Wallin to the victim. During the investigation police obtained unspecified evidence of the crime. He was arrested last Thursday at the High School.

Wallin was lodged in the West Valley Detention Center on charges of Unlawful Sexual Intercourse, Oral Copulation and Sexual Penetration With a Foreign Object. He is currently out on $100,000 bond.
