Ryan Cleary, 19, was arrested early last week in connection with a string of attacks on websites around the world. He was recently released on bail.
According to Reuters, Cleary is under a curfew between 9am and 7pm. Cleary's been electronically tagged. If he wants to leave his house, Cleary must be accompanied by one of his parents.
"I'm aware that I'm his best friend as well as his mother, because he's reclusive," Cleary's mother said in court.
Since his arrest, the 19-year-old has been diagnosed with Asperger's syndrome.
As previously posted, Cleary's mum said her son "lives his life online".
"I thought he was playing computer games in his room," she told the Mirror. "I can't believe it. He rarely left the house."
The now disbanded LulzSec claimed responsibility for a rash of recent attacks, including the CIA's website and the Battlefield Heroes beta.
