(KNZA)--A former Hiawatha High school biology teacher convicted of having unlawful sexual relations with an underage student has been sentenced to three years probation.

24-year-old Gabrielle Bauman, of Fairview, was sentenced Monday in Brown County District Court.

Brown County Attorney Kevin Hill says Bauman will have to register as a sex offender for 25 years.

She pleaded no contest in November to a felony charge of unlawful sexual relations.

Bauman was arrested in August after Hiawatha police investigated a report made to the school district administration in mid-June.

Bauman was convicted of engaging in unlawful sexual relations with a Hiawatha High School student, born in 1999, between November 2016 and May 21st of last year while she was a teacher at the high school.

Hill says the victim and victim's family asked that Bauman receive probation.

The Hiawatha Board of Education accepted her resignation in July.  Bauman had taught at the high school for a year.
