Ten days after the bombing, 25-year-old Judith Ward was arrested in Liverpool while waiting to board a ferry to Ireland. She was later convicted of the M62 coach bombing and two other separate, non-fatal attacks and remained incarcerated until her conviction was quashed by the Court of Appeal in 1992, with the court hearing Government forensic scientists had deliberately withheld information from her defence counsel at her October 1974 trial which strongly indicated her innocence. As such, her conviction was declared unsafe.
