Staff at West Ham United have been left red-faced after an error saw the email addresses of hundreds of season ticket holders shared among fellow fans.

According to the Daily Telegraph newspaper, the London club could face a data breach investigation after the error. The report added that West Ham has apologised to the fans involved, with the incident to be reported to the Information Commissioner’s Office.

West Ham had emailed fans to inform them of ticket details for next week’s EFL Cup match against AFC Wimbledon. Reportedly, up to 200 email addresses were shared.

Speaking to the Daily Telegraph, Ben Robson, a partner at the Oury Clark legal firm, said: “This would be a data breach because the purpose supporters gave their addresses to West Ham was not for it to be shared with every Tom, Dick or Harry.

“Given the scale, it’s certainly the kind of thing that is notifiable. It’s a pretty large-scale breach for anyone wanting to use the list for their own personal devices.”

In a follow-up email seen by Sky Sports News, the club wrote: “Beyond your email address, no other information has been shared.”

West Ham travel to third-tier team AFC Wimbledon in the second round of the EFL Cup next Tuesday.
