British teen arrested over cyberattack on London transportation agency

British authorities arrested an unnamed 17-year-old in connection with a cyberattack against Transport for London that the National Crime Agency says involved "suspicious activity" and led to limited customer data access, including some names, contact details and bank account numbers tied to cards; the suspect was detained on suspicion of Computer Misuse Act offenses and released after questioning. The report notes the incident is part of a trend of teenagers implicated in high-profile cyberattacks.
