A California high school teacher was arrested Friday on suspicion of having sexual relations with two students, officials said.
Lindsay Himmelspach, 33, allegedly had sexual relationships with two male students at two different high schools.
The sexual relationships were "brief in nature" and included the sharing of nude photos between Himmelspach and the two students, Butte County Sheriff's Department said in a statement. The events took place over summer break.
Authorities were tipped off to the alleged relations by the school superintendent, who reported a message from an anonymous caller about students having inappropriate relationships with a physical education teacher.
Officers arrested Himmelspach at Las Plumas High School in Oroville, California, where she teaches PE.
She was booked into the Butte County Jail on two counts of unlawful sexual intercourse with a minor, two counts of communicating with a minor for purposes of committing sexual acts, and two counts of communicating with a minor to commit a lewd or lascivious act.
Himmelspach has taught in the Oroville Union High School District for about 10 years, according to officials. She has been placed on paid administrative leave.
