A Co Antrim schoolboy arrested over the cyber attack on TalkTalk is suing three national newspapers for alleged breach of privacy.
Lawyers for the 15-year-old have also commenced proceedings against internet giants Google and Twitter.
The lawsuit centres on publicity surrounding his questioning last month by police investigating a major hack into the phone and broadband provider's database.
Details of the case can be disclosed after reporting restrictions were partially lifted by a judge at the High Court in Belfast.
Mr Justice O'Hara has also granted injunctions against Google and Twitter in a bid to remove any online references to the teenager's name, address, images or information about his physical appearance.
The three newspapers defending the action, The Daily Telegraph, The Daily Mail and The Sun, all gave undertakings aimed to protecting his identity pending the outcome of the case.
The boy was among four people to be detained in connection with the TalkTalk hacking probe.
He was interviewed on suspicion of offences under the Computer Misuse Act before being released on bail.
Since then his lawyers have issued writs claiming negligence, misuse of private information, defamation, breach of confidence and data protection.
The case is due to be heard again next month.
