High schoolers charged: Henry Sanchez, 18 (pictured) and Jose Montano, 17, have been charged with raping a 14-year-old female classmate in a Maryland high school bathroom

Disturbing new details have emerged in the case of two teenage immigrants living in Maryland, one of them illegally, who are accused of brutally raping and sodomizing their 14-year-old female classmate in a bathroom stall on campus.

The alleged assault happened Thursday morning at Rockville High School in Montgomery County, leading to the arrests of 17-year-old Jose Montano, from El Salvador, and 18-year-old Henry Sanchez, from Guatemala, on charges of first-degree rape and first-degree sexual assault.

A probable cause statement filed on Friday at the Montgomery County District Court by the arresting officer painted a harrowing picture of the rape, based on an interview with the alleged victim and physical evidence gathered at the scene.

According to the court document, obtained by the station WJLA, Montano and Sanchez accosted the girl in the hallway at around 9am Thursday.

The girl knew only one of the teens, Montano, who allegedly asked her for a hug, then slapped her butt and asked her to walk with them.

As the trio were passing by a boys’ bathroom on the way to the gym, the 17-year-old Montano repeatedly asked the girl to have sex with him and his friend, and when she refused they allegedly forced her into the restroom.

The probable cause document describes the assault in extremely graphic detail, recounting how the alleged victim grabbed onto a sink to avoid being forced into a stall, but the two suspects shoved her inside.

Once in the stall, the document states that Montano allegedly opened the girl's top and 'pulled her breasts out to play with,' then unbuckled her pants and pulled them down.

The two teenagers then allegedly proceeded to take turns holding down the young girl while forcing her to perform oral sex on them and raping her both vaginally and anally on the toilet multiple times while communicating with one another in Spanish.

Throughout the ordeal, the document stated, the victim screamed out in pain and repeatedly told her friend Montano, and Sanchez to stop.

After the horrific attack, police said Sanchez covered the victim’s head with his coat and led her out of the bathroom as Montano ordered her to be quiet.

The freshman girl immediately reported the assault to school administrators and law enforcement officials were summoned to the scene to investigate.

A forensic expert was later able to recover physical evidence in the form of blood and semen from the bathroom stall.

Henry Sanchez is believed to have entered the US illegally from Guatemala via Mexico seven months ago, at which time he was detained by a Border Patrol agent in Rio Valley Grande, Texas.

He is now facing deportation proceedings as he had a pending 'alien removal' case against him, according to the Washington Post.

Montano arrived from El Salvador about eight months ago. Immigration and Customs Enforcement won't report on his immigration status because he is a minor.

Despite their age, both the boys were placed in the ninth grade.

Montgomery County Public Schools Superintendent Dr Jack Smith on Monday told Fox 5 that Sanchez and Montano were enrolled in the Rockville school's multidisciplinary program for English learners.

Montano is charged as an adult, but police have not released his booking photo.

On Friday, Rockville High School sent a letter to parents addressing the incident and the arrests, according to WUSA.

'Ensuring a safe, secure and welcoming learning environment for all of our students is our top priority. Our staff remains vigilant in the monitoring of our school each and every day,' the note said in part.

Gboyinde Onijala, a spokeswoman for the Montgomery County Public Schools, said that staff at Rockville High will increase monitoring of the hallways and bathrooms. The school has one school resource officer.
