WICHITA, Kan. (AP) — A former Wichita high school music teacher has been sentenced to two years of probation for attempted unlawful sexual relations with a student.

Twenty-six-year-old Alan Martens was sentenced Wednesday. He had pleaded guilty in February. Prosecutors say Martens exchanged text messages that were sexual in nature with a female student at Wichita Heights High School.

It’s illegal in Kansas for teachers to have sexual relationships with students, even if the student is old enough to give legal consent. The age of consent in Kansas is 16. Court records say the student was at least 16.

Wichita public school district spokeswoman Susan Arensman has said that Martens was in his first year of teaching when he resigned in March 2015.
