An East Liverpool officer has resigned amid an investigation into accusations he sent "inappropriate messages" to a student, according to East Liverpool Police Chief John Lane. 

Officer Shawn Long resigned last week. He had been on paid administrative leave for just under a year until his resignation. 

According to Chief Lane, Long was placed on leave after Long allegedly sent the messages to the student on social media when he was a school resource officer for East Liverpool City Schools. 

Long had been with the department for more than 20 years, and according to Chief Lane, they had no other incidents involving Long. 

Chief Lane says the investigation is ongoing and is headed by the Ohio Bureau of Criminal Investigation. No charges have been filed up to this point. 

21 News reached out to East Liverpool City Schools for comment. Superintendent Jonathan Ludwig said it's imperative that the school finds the best officer they can moving forward and safety is a priority. He could not comment further since the investigation is ongoing.
