A former high school teacher in Texas has been indicted over accusations she had sex with four of her students.

According to a September 2011 search warrant, parents of a graduate and former student of Tonya Flink, 39, reported to police that their son was living with her at her apartment.

They told police that they believed the relationship began while their son was a senior at Haltom High School in Haltom City, which is near Fort Worth.

In the same month, investigators learned of other relationships, according to the warrant.

According to the report from police, the former student in question admitted that the relationship began when he would stay after school and Flink would help him with his grades. Flirting led to Flink "pushing herself onto him," according to police.

Flink would go on to tell the student that "she loved him," that she "liked young Hispanic kids like him" and that their eventual sexual relationship involved "everything you could imagine," police said in the warrant.

Police also reported that they found evidence that Flink made at least 850 phone calls to one of the students in question over a period of a few months.

Investigators also reported that she bought clothes for some of them and that she went to the home of one of her students and secretly knocked on his back door so she could meet with him.

According to police, Flink resigned from her position as a computer technology teacher at Haltom High in August 2011, shortly before police began their initial investigation.

Flink went on to teach for a time at Carter Riverside High School in the Fort Worth Independent School District, but resigned from her position long before the district ever learned of her alleged involvement with students, a district representative said.

She was indicted by a Tarrant County grand jury.

Flink is free after posting $10,000 bond. She is due in a Tarrant County courtroom next week, according to her attorney.
