18-year-old Arion Kurtaj, who is accused of participating in a hacking spree that resulted in leaked early gameplay footage of Grand Theft Auto VI, has been deemed mentally unfit to stand trial in a London court, according to Reuters.

As a result, the trial jury will “determine whether he committed the acts,” but won’t determine his guilt. Kurtaj was allegedly part of Lapsus$, a hacking group that gained notoriety for several high-profile cyberattacks last year.
