Authorities say when Motola was arrested he complained of chest pains and was taken to Ben Taub Hospital.

The Harris County District Attorney's Office said Rosales-Motola, 56, is charged with one count of indecency of a child and two counts of improper relationship with a student.  The DA's office said the charges stem from three separate incidents which occurred in May and October. All three incidents involved male students.

Sharpstown High School's principal, assistant principal and a counselor have been charged with failing to report child abuse.

Officials said Principal Rob Gasparello, 58, and assistant principals Silvio Leiva, 50, and Jason Thomson, 28, were all arrested Thursday afternoon. 

According to criminal complaints, two students told Gasparello that Rosales-Motola, a Spanish teacher, had touched them inappropriately. Documents show Thomas and Leiva helped those students translate their allegations to Gasparello. 

Court records state that on October 3, a 17-year-old boy reported that he was inappropriately touched by Rosales-Motola in his classroom when the student stayed after school.

According to court documents, on October 10, another 17-year-old boy told his ESL teacher that Rosales-Motola used his hand to touch the boy inappropriately after school in the teacher's classroom. The student and the ESL teacher then told Principal Gasparello and Thomson about what had happened.

Detectives say Gasparello and Thomson did not report the alleged incident to police.

Houston police began investigating on October 24 after they learned about the allegations.

Court records show another incident, which occurred on May 22, involved a 16-year-old boy and Rosales-Motola, where the teacher inappropriately touched the victim in his classroom.

Authorities said Gasparello also did not report an October 19 incident that involved a 16-year-old girl who said she was sexually assaulted before school. Officials said this incident did not involve Rosales-Motola.

During a press conference Friday morning, DA Devon Anderson said everyone has a moral obligation to report suspected child abuse.

"It doesn't matter who you are, if you fail to protect the children in your care and you don't report it to authorities, we will prosecute you," Anderson said.

The DA's office said suspected child abuse must be reported to a law enforcement agency or Child Protective Services.

Authorities said Rosales-Motola did not show up Friday morning at the high school.

Houston ISD released the following statement Friday afternoon about the investigation:
"HISD is fully cooperating with this investigation. Like Harris County DA Devon Anderson stated, it's everyone's moral duty to report any suspicion of potential child abuse. All of our district professionals are trained and obligated to report, within 48 hours, all incidents and circumstances in which it is believed that a child's physical or mental well-being has been adversely affected by abuse or neglect by any person.   
"The principal and assistant principals charged with these allegations have been removed from the school pending the conclusion of this investigation.   Since these are criminal charges, HISD will NOT provide legal counsel or financial support to the accused employees."

Gayle Fallon, president of the Houston Federation of Teachers, said her union represents that teacher.

"The principal investigated and said there was nothing to it," said Fallon. "They cleared the teacher. There was no basis for the charge."

The school district said Houston police launched their own investigation.

Parents are shocked by the allegations of child abuse and afraid for the safety of their children.

"I would've never thought something like this was going on," said Fred Slone who has a son who attends the school. "My kid is scared to come to school."

Slone said he won't send his son back to Sharpstown High until he gets more information on what is going on there.

"We were shocked," said a student. "I believe he's such a great principal though."

Local 2 tried to reach Gasparello at his home but no one answered the door.

Thomson and Leiva face one count and each posted their $1,000 bond. Gasparello is charged with three counts and posted bond set at $1,500 for each count.
