WOODBURY - More than a half-dozen convicted sex offenders are back behind bars as part of a brand new measure designed to protect communities from predators.

Suffolk authorities say eight registered sex offenders have been arrested for various parole and probation violations, such as using social media or failing to update their address and picture with the New York State Sex Offender Registry.

County officials say the arrests came just weeks after the county implemented the Community Protection Act, which allows Parents for Megan's Law to act for police by monitoring offenders' online activity, verifying their addresses and streamlining that information for police.

Sex offenders Troy Wallace and Carlos Perez have recently filed a lawsuit against County Executive Steve Bellone and Parents for Megan's Law Director Laura Ahearn, claiming that the new law violates their civil rights.
