A statement from the North East Counter Terrorism Unit (NECT) said the six were arrested on suspicion of preparing an act of terrorism.
Police are still searching six properties in London and two other cities as part of the investigation.
The series of dawn raids was led by the NECT and supported by local officers from Derbyshire, Staffordshire and the Metropolitan Police.
Some local residents are concerned about the police operation happening so close to their homes.
Brett Granger, a 26-year-old man living only a few doors down from where police swooped in Derby said he was “shocked to see people in army uniforms” outside his door. He told local media, the Derby Telegraph, it is “scary to think things like this are happening so close to home.”
City councilor Fareed Hussain, who represents the area in Derby where the investigation is taking place told the local news website “it’s a shock to the system”.
Officers will be patrolling the areas to speak to anyone with concerns, according to the NECT.
Britain is on its second highest threat level, which means a terrorism attack is “highly likely”.
Andrew Parker, the head of MI5 has claimed there may be around 3,000 homegrown Islamist extremists operating in the UK.
Meanwhile, fears of Christmas attacks in Britain is growing. The Special Air Service (SAS) and police will monitor high streets and shopping centres across the country during the Christmas season.
Last Friday a 41-year-old man was arrested at Stansted Airport on suspicion of preparing terrorist acts.
