 McGrady came under the influence of Floyd McClung, a leading member of the religious organisation who persuaded McGrady that to make progress within the organisation, he had to "repent of his past sins" by returning to Belfast and confessing to the Royal Ulster Constabulary about his previous IRA activities.Following McClung's advice, McGrady returned to Northern Ireland and on 12 January 1982, he entered Musgrave Street Police station and made his confession to the police, admitting to IRA-related offences.He was arrested and sent to Crumlin Road Prison.
