Reports about hacking done on the TalkTalk website surfaced last week. A 15-year-old boy was arrested in Northern Ireland relating to the TalkTalk security breach, according to Scotland Yard.

The boy, who allegedly violated the Computer Misuse Act, was captured after a house had been searched by the authorities in County Antrim on the afternoon of Monday, Oct. 26, at around 16:20 GMT.

"An arrest has been made in connection with the investigation into alleged data theft from the TalkTalk website," said a Scotland Yard spokesperson.

The young man was brought to the Antrim police station and was interrogated by the Police Service of Northern Ireland's investigators.

The probe, which still continues at the moment, is a joint effort of investigators from the Metropolitan Police Cyber Crime Unit (MPCCU) alongside the Police Service of Northern Ireland (PSNI).

The criminal investigation commenced as early as Thursday, Oct. 22.

Previously, TalkTalk reported that its consumers' banking details and personal information could have been illegally penetrated.

The chief executive of TalkTalk, Dido Harding, likewise said the company does not know how many U.K. customers were hit by the hack. The attack impacted the website of the telecom giant, instead of the company's core systems.

To date, the phone and broadband provider boasts more than four million customers in the UK.

Meanwhile, TalkTalk issued a statement in connection with the progress of the investigation.

"We know this has been a worrying time for customers and we are grateful for the swift response and hard work of the police. We will continue to assist with the ongoing investigation," TalkTalk said.

Meanwhile, the company is advising its consumers to head over to https://talktalk.co.uk/secure for more updates and information in relation to the incident.

On Oct. 26, it was reported to the public that the company's executives are to be called before MPs to explain how hackers were able to take away the bank details of its customers.

Ed Vaizey, the culture minister, also told the House of Commons that the companies with their consumer data is not prohibited to practice compulsory encryption. The probe into the hacking is headed by Jesse Norman, the chair of the Culture, Media and Sport Select Committee.
