A teacher from California who is the wife of a US Army Lt Col has been arrested after a pupil recognized the teacher as appearing in a video on a porn website.
The student noticed the youngster in the clip as being a classmate and as underage female family member.
The teacher, who is a mother-of-two, Dawn Giannini, 49, from Palo Alto remains in custody while the investigation continues, the Daily Mail reports.
The teen who spotted the teacher in the raunchy clip online had been looking at PornHub.
They then alerted the school's principal, who called police, which resulted in Giannini's arrest.
Giannini who is married to Thomas, a US Army Lieutenant Colonel, and one of the most senior positions in the Army, was a fourth grade teacher at St. Elizabeth Seton Catholic School in Palo Alto, in 2015.
Before that, she was a special education assistant and substitute for the Redwood City School District.

Redwood City School District Superintendent John Baker sent out an email to parents about Giannini and said while it is believed she did not assault a student, the information is still "truly heartbreaking".
San Mateo County District Attorney Steve Wagstaffe would not identify how Giannini and the young girl, who was 14 at the time of the crimes, were related.
Giannini is accused of having a sexual relationship with the underage family member from November 2014 until November 2015.
Giannini is alleged to have recorded some of the sexual interactions, which were then later uploaded onto the PornHub website.
Prosecutors believe the girl posted the video.
The allegations will have brought shame on the family of four which include the Giannini's two teenage children.
Her husband, Thomas, is a high-ranking military officer who has had three overseas deployments to Iraq and Afghanistan.
He also has proven leadership experience as a company commander, Battalion Operations Officer and most recently as an Area Office Officer-In-Charge coordinating several Afghanistan Infrastructure Projects in remote locations, while serving in an active combat zone.
His wife now faces two dozen charges including seven counts of lewd act on a child, six counts of oral copulation on a child under 16 years old, six counts of sexual penetration with a foreign object, one count of showing porn to a child and one count of incest.
"We know the victim was sexually active, and there were a lot of videos that were uploaded," DA Wagstaffe said.
"We know that this occurred in at least two counties. It occurred here in our county, in Redwood City and there was a trip down to Santa Cruz that she took with the victim and there was sexual activity there."
