Police have arrested a 41-year-old man in connection with distributed denial-of-service attacks against the websites of the Home Office and home secretary Theresa May.
Officers from the Police Central e-Crime Unit in London, and from its East Midlands hub, arrested the man in Stoke-on-Trent on Tuesday on suspicion of encouraging cyber crime.
Police seized computers, telephones and media storage devices, and the man was bailed to return to a local police station in mid-December pending further enquiries, the Metropolitan Police said in a statement on Tuesday.
"Assisting and encouraging cyber crime is a serious matter and I would advise all persons to consider their actions and any possible future consequences prior to posting any material online," said Police Central e-Crime Unit detective inspector Jason Tunn.
The Anonymous hacktivist group claimed to have launched a series of distributed denial-of-service (DDoS) attacks against the Home Office and Theresa May in April this year.
