Raleigh, N.C. — Wake County Sheriff Donnie Harrison said Friday additional charges could be filed against a former coach and educator accused of indecent liberties with a child.

John Peter Skatrud, 41, of 103 Mantle Court in Raleigh, was charged on Thursday with three counts of indecent liberties with a student and one count of sexual offense with a child.

Harrison said the charges were filed as part of an ongoing investigation.

“Anytime you're dealing with this type situation it’s going to take some time, but we continued our investigation and we got enough evidence to make some charges and the investigation is going to continue,” Harrison said.

Skatrud, who coached volleyball at North Carolina State University and for the Capital City Volleyball Club, was working as a physical education teacher at Yates Mill Pond Elementary School at the time of his first arrest in February. He was indicted on two counts of indecent liberties with a child and two counts of indecent liberties with a student in March.

All of the charges involve victims who are 7 or 8 years old, according to authorities.

“If parents do have some concerns they can feel free to call us. If they have any information they think we should know I would prefer they call our investigation division and see what we can do,” Harrison said.

Skatrud was released Friday on a $150,000 bond.

On Friday, Skatrud's attorney, Hart Miles, appeared in court on his behalf and suggested his client might be looking for a plea agreement.

"We hope to resolve this case without a trial," Miles said.
