Alyssia Marie Reddy, who taught at the Pennington School located in Pennington, New Jersey, came to the attention of police after the Solebury Township department received a report of an alleged sexual assault that took place in the park in the spring of 2017, multiple news outlets are reporting.

Authorities said Reddy, who currently lives near Baltimore, had sexual intercourse with the student.

She was arrested on charges of institutional sexual assault, unlawful contact with a minor, criminal use of a communication facility and corruption of a minor, according to a release issued by the Solebury Township Police Department.

The Pennington School where Reddy worked sent a letter to parents saying that it had been "recently made aware of an alleged inappropriate relationship involving a former Upper School teacher of The Pennington School in the 2016-17 school year," according to a report by the Trentonian.

WCAU reported that Reddy gave the student her cellphone number in December of last year and that by February 2017 he was getting messages like, "I want your hands on me."

The school also said that upon hearing the incident, it quickly made contact with the Mercer County Prosecutor’s Office.

Reddy had apparently departed from the New Jersey prep school and was employed at The St. Paul's School for Girls located in Baltimore County. Her Facebook page said that she is a SPIRITUS Scholars Coordinator and History Teacher there.

The school terminated her employment following her arrest and banned her from the campus. It also deleted references to Reddy from its website, but a Google search showed that she was recently in the staff and faculty directory.

"We have just learned that one of our Upper School teachers, Alyssia Reddy, who joined our faculty this year, has been charged with a felony involving sexual assault of a minor," Head of St. Paul's Penny B. Evans said in a letter obtained by WPMT.

“The alleged events took place in Pennsylvania this past school year with a male high school student before she came to St. Paul’s School for Girls. Before today, we had no information suggesting any prior improper conduct by Mrs. Reddy.”

On her Facebook page, Reddy has published many pictures of what appear to be her husband and two children, according to the Trentonian.

She is currently awaiting extradition to Pennsylvania.
