A high school teacher in Nevada was arrested Monday on kidnapping charges after “inappropriate messages” between her and a student were found, police said.

Breanna K. Hernandez, a 27-year-old teacher at Basic Academy of International Studies in Henderson, is facing two counts each of first-degree kidnapping, lewdness with a minor and luring a minor, Clark County School District police announced.

Hernandez was arrested after a months-long probe was launched in November when authorities were first alerted to “inappropriate messages” between her and the student, Lt. Darnell Couthen said. It was not clear why the kidnapping charges were warranted.

Hernandez, who was hired by the district in 2015, had been reassigned to work from home since the start of the criminal probe, Couthen said.

Messages seeking comment from school district officials and Hernandez’s attorney, Richard Tanasi, were not immediately returned Tuesday.

Hernandez, who was taken into custody at the Clark County Detention Center, is scheduled to make her initial court appearance Tuesday, jail records show. A search of the school’s website did not return any additional information on the teacher.
