Prison Fellowship mobilises and assists volunteers from the Christian community, through prayer, practical action and values-based programmes, to restore those affected by crime - offenders, ex-offenders, families, victims and communities. Specific initiatives include Sycamore Tree, a victim awareness programme for prisoners based on restorative principles; Angel Tree, helping to strengthen family ties by providing Christmas presents for prisoners' children; and Compass, a Christian values-based programme covering life skills, lifestyle and the arts. Volunteers are based in more than 150 local groups.
