A 28-year-old man from Worksop has been arrested as part of a national drive to deter cyber hacking.
He was among seven people across the country questioned about their separate online activities. He has been released under investigation into suspected computer misuse.
The action was part of a week-long operation coordinated by the National Crime Agency and the West Midlands Regional Organised Crime Unit.
Detective Inspector Paul Carrington, from the East Midlands Special Operations Unit’s Cyber Crime Unit, said: "People’s motivations for getting involvedin cyber crime can range from financial reward, to solving a complicated technical problem or bypassing a network’s security for the sake of a challenge.
"Sometimes it’s part of a wider criminal enterprise and sometimes it’s a sole actor. Either way cyber crime can be an extremely intrusive and disruptive offence, resulting in significant financial or service loss, as well as the misuse of personal information — something we cannot and will not tolerate".
