West Ham United inadvertently leaked details of supporters - including names, home addresses and phone numbers - on their official website after a 'technical error' while accessing the ticketing system, reports claim.
Fans attempting to log on to the club's ticketing system earlier this month were greeted with several error messages, with some shown personal details of supporters, according to Forbes - potentially leaving them at risk of phishing attacks.
Some supporters were greeted with a message from Drupal - a web platform - that read 'Drupal already installed', while others were able to see the names, dates of birth, email addresses and phone numbers of fans.
