Former Bethlehem school police officer charged after alleged sexual relationship with student

BETHLEHEM, Pa. (CBS) -- A Lehigh Valley school resource police officer and soccer coach is accused of taking an inappropriate video of a young girl and having a sexual relationship with another girl.

Prosecutors allege 43-year-old Costas Nick Alestas had a sexual relationship with a 14-year-old student and recorded at least one upskirt video of an 11-year-old girl.

Police said Alestas was a school resource officer for six years at East Hills Middle School in Bethlehem. He was also the school's co-ed soccer coach, according to court documents.

During a press conference on Wednesday, police said they were notified by the Bethlehem Area School District of Alestas's alleged "inappropriate" relationship with a student on May 1. Alestas was immediately asked to leave the school and was placed on administrative leave.

Through their investigation, they said the school resource officer had multiple sexual encounters both on and off school grounds with the 14-year-old girl.

Court documents also allege Alestas had at least one video on his personal phone showing up an 11-year-old girl's skirt, unknowingly recorded.

Alestas is charged with six offenses including statutory sexual assault, sexual contact with a student and invasion of privacy.

The school district declined further comment on the matter Wednesday and pointed us to a message posted to their website .

The statement reads, "Upon receipt of information indicating an alleged relationship between a student and a Bethlehem Police Department School Resource Officer and soccer coach serving East Hills Middle School, the Bethlehem Area School District immediately began its investigation and notified all mandated agencies. The staff member was placed on administrative leave by both the BASD and Bethlehem Police Department. The alleged inappropriate behavior violates community trust in our schools, undermines safety, and is illegal, intolerable, and inexcusable. Our students' physical and emotional safety has been and will continue to be the BASD's first priority. The BASD will provide counseling support as needed. The BASD remains committed to transparency and cooperation with all investigative and legal entities as it relates to this matter."

The district adds it's cooperating fully and providing counseling to students and staff.

Court records show Alestas was unable to post bail and remains in the county jail.

He is due back in court later this month.
