An investigation is underway in Old Lyme after sexual emails were sent from a teacher's computer to parents and administrators.
State police said they are looking for the person who gained access to a teacher's email account sent the sexually explicit emails.
The incident occurred Wednesday night. Although the messages were sent to parents and staff members, officials said most students did not receive them.
"I believe the majority of our students did not see it because we were able to shut down the e-mail system prior to students coming back to school the next day," said superintendent Ian Neviaser.
Part of the reason few students saw them was because the district's I.T. department deleted the emails after they disabled student access.
State police are investigation who gained access to the account and how.
They are unsure if it was an internal email distribution accessed outside the system.
"Sometimes there are security breaches it happens you know and We have to decide if we want to live with that or not," said parent Alison Ritrovato.
Educator and parent Margaret Lavezzoli said the school is being forced to learn an important lesson on cybersecurity.
"Having been a teacher myself I would have been highly embarrassed. What do you do? How do you have a secure website or secure e-mail," said Lavezzoli.
If the person responsible is caught, officials said they could face cyber crime charges.
The school district will enforce disciplinary action if it is a student or employee.
