US police have arrested more than 10,000 fugitives in just six days, in what they say is the largest operation of its kind in US history.
More than 150 murder suspects were arrested
More than 3,000 federal and local officers made the arrests during Operation Falcon, from 4-10 April.
Attorney-General Alberto Gonzales said law enforcement officers primarily targeted violent offenders.
The number of fugitives arrested is about 10 times as many as were detained in the same period last year.
"Fugitives belong behind bars, and the arrests of 10,340 fugitives translates into safer communities," said Ben Reyna, director of the federal US Marshals Service, the Reuters news agency reported.
Operation Falcon, which stands for "federal and local cops organised nationally", marked the first time that US Marshals teamed up with state and local law enforcement teams in a concentrated, nation-wide effort to round up fugitives.
Officials said they did not have figures for how many federal, state and local fugitives remained at large.
A total of 162 murder suspects, 553 rape or sexual assault suspects and 154 gang members were arrested, US Marshals said.
In addition, 638 armed robbery suspects and 68 kidnapping suspects were held.
