Previous story from The Associated Press:

Police are investigating reports that some students at Orlando's Lake Nona High School circulated nude photos of classmates.

According to a school resource officer's report, a parent complained after receiving a nude picture of her daughter in an April 27 text message.

The Orlando Sentinel reports the parent asked for the officer's help in finding out who sent the picture of her daughter.

It was unclear how many students were involved.

Students' names were redacted from the report. One student told the officer that she had sent the picture and realized she was wrong for doing so. Another said someone sent him nude pictures several weeks earlier and he shared them with a fellow student.

School officials said they're also following up with parents.
