ROCK HILL, S.C. -- Disorderly conduct charges have been dropped against seven people arrested after officials say they disrupted high school graduation ceremonies by cheering while names were being read.

The Herald of Rock Hill reported Tuesday that charges were dismissed after the defendants wrote apologies for their behavior.

Attorney Harry Collins and Rock Hill prosecutor Chris Barton say an eighth person arrested likely will get the same deal, but he has been unable to sign an apology because he was in a traffic accident.

Those arrested were attending graduations for Fort Mill, York Comprehensive and Northwestern high schools. School officials have said that inappropriate cheering has become a growing problem at the ceremonies.
