Almost 550 New Jersey fugitives were arrested last week as part of a national crackdown called Operation Falcon.

New Jersey law enforcement considers those arrested some of the nation?s most violent fugitives. Authorities say it took them months to find the fugitives, but only a week to round them up. Officers in NJ brought in wanted sex offenders, unregistered sex offenders and documented gang members.

This is the operation?s third and, according to police, most successful year. In all, the U.S. Marshals Service was able to round up almost 11,000 fugitives nationwide.
