Backstreet Boy Nick Carter has finished his pre-trial prevention program following his arrest for lewd behaviour outside a Florida, America nightclub in January.

At the time, the singer did not take his arrest well, according to another witness.

"He was being all loud and causing problems. At the end of the night there was a big fight. Cops told Nick and his friends to leave but they wouldn't," a witness reports.

The intervention program required the heart-throb to complete community service, pay a fine and stay out of trouble.

After successfully completing the program, the charges have been dropped and his criminal record will remain clean.
