A 27-year-old man and a teenage girl have appeared in court following an investigation into jury tampering.
Jonaade Hussain and the 15-year-old girl - who cannot be named because of her age - were arrested on Thursday and subsequently charged with conspiracy to pervert the course of justice.
West Yorkshire Police's investigation was linked to a "cash for crash" trial in February which saw four men jailed for a total of 37 years for offences including manslaughter and fraud.
In September 2014, they had staged a collision in Leeds to cheat money from insurers - but the crash killed Betty Laird, an 88-year-old woman.
Hussain appeared before Leeds Magistrates Court on Saturday, while the teenager attended a hearing at Leeds Youth Court. He was remanded in custody and the girl was released on bail.
Police are still questioning a 28-year-old man who was arrested alongside the pair.
