An area high school is the focus of two police investigations.

Kerrville Police told KENS 5 that two Tivy High School teachers are accused of having improper relationships with students.

Investigators are releasing very few details about the separate cases.

No one from Kerrville ISD would agree to an interview with KENS 5, but verified the authenticity of a letter we received from a viewer that came from Kerrville ISD.

The school district's Superintendent, Dr. Mark J. Foust, sent home the letter to parents letting them know the two teachers are on indefinite administrative leave due to separate and unrelated allegations of improper teacher/student relationships at Tivy High School.

The letter went on to say, "The safety and well-being of our students is our first and most important priority. These allegations are of behaviors that will not be tolerated in our school district and that are not indicative of our faculty and staff."

Kerrville Police say the first complaint that sparked this investigation came in last Thursday.

"We got the first one, started it, then we received information of a second completely separate allegation and then started that investigation," said Lt. Mary Krebs, Kerrville Police Department.

Authorities won't say if the relationships were believed to be sexual in nature, ongoing, or one time encounters.

"At this time we can tell you they are isolated incidents and there are no threats to any students at the high school," said Krebs.

Police say parents should know these allegations are being taken seriously.

"We have some outstanding investigators and we will get to the bottom of this," said Krebs.

Police have not released the teachers names because they have not been charged with any crimes at this time.
