Delta Quadrant species whose government imprisoned Tom Paris and Harry Kim for a bombing they did not commit, in a lawless prison fed through a chute.
The Akritirians are a Delta Quadrant people whose homeworld is Akritiri. Their justice system treats a confession as final, and convicts are sent to a prison where food arrives only through a chute and each inmate carries a neural implant called the clamp, which steadily heightens aggression and erodes sanity.
In The Chute, Paris and Kim were framed for a trilithium bombing and sent there. Even after Voyager caught the real bombers, Ambassador Liri refused to reopen the case, so Janeway learned that the prison was actually a space station and staged a rescue of her two officers.
