The 15-year-old arrested by police investigating a cyber attack at TalkTalk has been bailed.
Police arrested the teenager at his family's home in Ballymena, Northern Ireland, on Monday. He was released on bail on Tuesday morning after being questioned by detectives overnight and will be required to report back to police next month.
Neighbours at the family's Unionist estate said that the police were still there at 11pm on Monday night. Kathy Haveron, 39, told the Telegraph: "I got home from my mum's at 11pm last night and there were still police around. They were around most of the night."
The teenager was arrested on suspicion of Computer Misuse Act offences.
His age came as a shock to security experts who believed that Russia or Isis was behind the attacks.
TalkTalk, a phone and broadband provider, said at the time that it has suffered a DDoS attack, where a website is bombarded with traffic. It said there was no evidence that customer's bank accounts have been affected but that it does not know how much information was encrypted.
