A brutal Akritirian maximum-security prison, secretly located aboard a space station, where Tom Paris and Harry Kim are held after being wrongly convicted of a bombing in the Voyager episode The Chute.
The Akritirian prison is an unsupervised detention facility into which inmates and occasional food are dropped through a metal chute. It appears in the episode The Chute, set in 2373.
Paris and Kim are sent there after a terrorist bombing on Akritiri, convicted because the explosive used trilithium. Every prisoner carries a neural implant known as the clamp, which steadily raises aggression until the inmates turn on one another. Paris is stabbed, and Kim struggles to protect him while holding on to his own sanity.
Kim climbs the chute to escape, only to find that the prison is not underground but aboard a station in orbit. Janeway meanwhile catches the real bombers, and when the Akritirian authorities refuse to reopen the case she uses Neelix's ship to dock and pull the two men out.
