The U.S. Marshals Service says it has rounded up 7,100 fugitives in a six-week nationwide sweep that focused on seven cities shown to have a high number of people wanted by the law.

Director Stacia Hylton joined law enforcement officials in Camden, New Jersey, on Thursday to announce the results of the effort called Operation Violence Reduction 7.

Hylton says the effort focused on finding the most dangerous fugitives in seven cities and surrounding areas.

She says those arrested included 519 people wanted for homicide and 583 for sexual assault.

She says 10 missing children were also located in the sweep.

Besides Camden, the operation took place in Atlanta; Baltimore; Chicago; Fort Lauderdale, Florida; New Orleans; and Oakland, California.

There were 84 arrests in Camden.
