LUMBERTON, N.C. (WNCN) – More than 120 people were arrested as part of a major crime initiative in Robeson County, the U.S. Marshals Service announced Friday.

“Operation Zero Hour” resulted in 170 warrants served, 123 arrests and 22 firearms being seized, including rifles, handguns, shotguns. A bulletproof vest was also seized.

The U.S. Marshals Service said 37 high risk searches were conducted as part of the initiative. Authorities were able to confirm 18 gang members.

“We were going after the worst of the worst,” said Scott Parker with the U.S. Marshals Service. “We arrested people for murder, accessory to murder.”

Others were arrested for child sex offenses, cocaine distribution, attempted rape, among other offenses.

Many of those arrested are being held in Robeson Count Jail. Authorities said some will be moved to Raleigh where they will face federal charges.

An undisclosed number of fugitives are still on the run, so the operation is ongoing.
