A man has admitted carrying out a number of high-profile cyber attacks on police websites and British Airways.
Paul Dixon, 23, caused mayhem when he took down the websites of Police Scotland, Durham Constabulary, Cex and British Airways.
It was claimed he cost British Airways up to £100,000 after he disabled the website for one hour.
The 23-year-old denied the offences which took place between October 16-26 2014 at Newcastle Crown Court last May, but changed his plea as the trial was
due to begin.
Dixon pleaded guilty to five counts of unauthorised access to computers with intent to impair by denial of service to legitimate customers.
Judge Stephen Earl told Dixon: "In relation to this matter you have pleaded guilty, therefore will be sentenced.
"From this moment you are subjected to bail at your home in Seaham, where you must stay every night.
"Should you breach these terms or commit a further offence your bail will be removed."
Dixon, of The Avenue, Seaham, County Durham, is due to be sentenced at 10:30am on May 4.
