Piri
Piri was an Akritirian female born in 2359. 

She and her brother, Vel, were members of a terrorist group called Open Sky that killed 47 people in a terrorist bombing in 2373. Based on circumstantial evidence,  crewmembers Tom Paris and Harry Kim were convicted of the crime and sent to an Akritirian maximum security detention facility located in space. Captain Janeway captured Piri and her brother in the course of investigating the bombing; despite their confessing to being involved in the bombing, Akritirian law did not provide for the admissibility of any new evidence after conviction and did not release Paris and Kim. In exchange for her brother Vel providing Janeway the location and shield codes of the prison so the two Starfleet officers could be retrieved, Piri and Vel were released without being reported to the authorities.
