A janitor at Calhoun Middle School — who was arrested by Denton police last week on a charge of indecency with a child-sexual contact — remains in Denton County Jail.

Ambrocio Mata of Denton, who turns 62 on Wednesday, is accused of having sexual contact with a 12-year-old boy at the school, police said.

Mata was transferred to Denton County Jail on Sunday, according to Denton police Officer Ryan Grelle. As of Monday evening, Mata remained in county jail in lieu of $250,000 bail, jail records state.

According to a copy of the arrest warrant affidavit obtained through the Denton Police Department, Mata is accused of having the student touch him inappropriately.

According to the affidavit, another custodian reported to a school resource officer Oct. 29 that he had witnessed Mata and the student in a classroom by themselves, standing close to one another.

When the student saw the other custodian, he immediately ran to the other side of the room, according to the report.

Police are also investigating other reports and surveillance video footage from the school, according to the affidavit.

School district Superintendent Jamie Wilson said an investigation by campus administrators and reports by school staff led to the allegations against Mata. There’s no indication any other students were harmed, he said.

Mata joined the district’s custodial staff in 2005, according to district officials. Since his arrest, he has been terminated, Wilson said.

Letters stating that an arrest warrant had been issued for Mata were sent home to parents last Thursday.

Carlos Ramirez, Calhoun Middle School principal, wrote in the letter that district officials “are working closely with Denton police to thoroughly investigate this incident and respond in a way that protects the safety and security of our students.

“I want to stress that Calhoun Middle School prioritizes the safety of our students. In addition to fostering a supportive environment, we also employ a variety of safety measures including: video surveillance of our campus, consistent two-way radio communication by administrators and a continued partnership with the Denton Police Department through our Student Resource Officers.”

Mario Zavala, a district spokesman, said the district’s main goal is to “stay proactive and not reactive.”

“We’re maintaining constant communication with the Denton Police Department through our school resource officer,” he said.
