Teenager arrested over London transport cyberattack

LONDON: A teenager has been arrested following a cyberattack on London's public transport body last week in which some personal customer data was accessed, the National Crime Agency (NCA) said on Thursday.

Transport for London (TfL), which operates the capital's tube and bus networks with millions of journeys each day, said it was contacting around 5,000 customers whose bank account data may have been accessed in the Sept. 1 incident.

Other customer data including names and contact details had been accessed, it added.

The NCA, which is investigating the cyberattack alongside TfL and the National Cyber Security Centre, said a 17-year-old male had been arrested in the central English town of Walsall and later released on bail.

"We ... are working at pace with our partners to progress the investigation," Shashi Verma, TfL's Chief Technology Officer said in a statement, adding that it was taking measures to improve security, including an all-staff IT identity check.

Verma said TfL did not expect any significant impact to customer journeys but that some temporary disruption was possible.
