(CNN/KEYE) - A female teacher at Lockhart High School turned herself in after they issued a warrant for her arrest for an improper relationship with a male student, according to the Lockhart Police Department.
Police said Sarah Fowlkes, 27, is suspected of having an inappropriate relationship with a 17-year-old male student at the school.
According to Lockhart ISD, administrators were told of the report just before spring break.
"It shocked me, especially since I used to go here," graduate Joe Chapa.
The districts said Fowlkes is an anatomy, physiology and environmental systems teacher.
"I just feel like the teacher should know better than to do that," Chapa said.
According to the district's website, this was her first year teaching at the high school. She previously taught at Lockhart's plum creek elementary school.
Parents picking up students at Lockhart High School Monday said they were surprised and disappointed.
Some added that the social media age doesn't help teachers and students keep things professional.
"I feel like it makes it easier for an accidental relationship for that to happen," Chapa said.
"I think maybe there's not as much of a distance as there should be. It should be much more professional," graduate River Morgan said.
In a letter sent to parents, district superintendent Susan Bonn said:
"Dear LHS Parents and Guardians,
I am writing to you with very upsetting news. Today, local law enforcement arrested Sarah Fowlkes,a teacher at LHS, for an improper relationship with a student.
On the afternoon of Friday, March 10th, the LHS administration received a concerning report. The principal notified district administration, and we immediately contacted law enforcement and Child Protective Services for investigation.
Fowlkes will not return to the school district. The district is sending notice of the conduct to the State Board for Educator Certification.
Every day, you trust your children to our care, and it is a responsibility we do not take lightly. As a parent of a Lockhart ISD student, I join you in feeling anger and disappointment in what happened.
As an administrator, I will always take swift action against anyone who would violate the sacred trust between students and educators.
Please take time to speak to your child about what has happened. If any student or parent has information about this situation, please contact the Lockhart Police Department at 512-398-4401.
The campus will have counselors available to meet with any student who needs or wants support.
In the meantime, if you have any concerns, please do not hesitate to contact me at firstname.lastname@example.org. I will be checking emails and will follow up with you as soon as possible.

Fowlkes earned a bachelor of science in biology from St. Edward's University.
Bohn said Fowlkes will not return to the school district.
She was booked into the Caldwell County Jail.
