A special education assistant at Ulysses S. Grant High School in Valley Glen was arrested this week on suspicion of possessing child pornography and has been “reassigned” from the school, according to authorities and school officials.

Grigor Agdayan, 42, of North Hollywood was arrested on April 4 on suspicion of possessing child porn, according to Los Angeles Police Department Officer Rosario Herrera and public records. The case is being investigated by LAPD’s Juvenile Division.

According to Los Angeles County inmate records, Agdayan bailed out and was released on Thursday. He had not yet been charged by prosecutors as of Friday morning.

In a letter sent to students’ parents obtained by the Daily News, Principal Pamela Damonte noted that Agdayan was arrested for “alleged sexual misconduct.” She said the April 4th incident “occurred off campus and did not involve any students.”

The Los Angeles Police Department notified LA School Police and the school about Agdayan’s arrest, according to the letter.

“The school and the Los Angeles Unified School District take these allegations very seriously and will fully cooperate with the police investigation,” Damonte wrote.

They will also take “every precaution” to ensure the safety of students and staff at their schools, she added.

LAUSD will also provide intervention counselors to work with students who may be impacted by the special education assistant’s arrest and removal, according to the letter.

Agdayan was hired as a substitute special education trainee in September of 2000, according to LAUSD officials. He became a permanent special education trainee at Grant High in March of 2001, and had been working at the school in this capacity six hours as day. His annual salary is $25,138.

Special education trainees assist teachers in caring for the physical needs of students with disabilities and in presenting educational material and developmental exercises while learning the duties and responsibilities of a special education assistant, according to the district’s job description.

In a statement Friday LAUSD Interim Superintendent Vivian Ekchian called the allegations — which she noted have yet to be proven —”extremely upsetting.”

“We will remain vigilant in protecting our students from those who would do them harm,” she said.

Agdayan has a court date set for April 26 at the Van Nuys Courthouse, according to county records.

He could not immediately be reached for comment on Friday.
