TITUSVILLE, Fla. (AP) - Two central Florida middle school students claim they were forced to clean the school's toilets as punishment.

The two sixth-grade girls at Riverview Elementary School in Titusville say they had to clean the toilets Friday because someone had written vulgar graffiti on the bathroom stall. The culprit never came forward, so the principal made 16 girls clean it up.

But Principal Shannon McClutcheon told WKMG TV in Orlando that the girls only wiped the toilet seats to get rid of some of the cleaning fluid that spilled, and that the unconventional punishment came after other options failed.

Only the two girls had to clean up the fluid that fell on the toilets.

McClutcheon says parents will be notified before a punishment like this is issued again.
