 Parker 's murder led to increased racial tensions in Peterborough . At his former school , three Asian pupils were suspended for an attack on an Afro @-@ Caribbean pupil ; a relative of the victim then attacked an Asian teacher . A number of taxi firms stopped work early in the days after the attack in fear of reprisals . In November 2001 Home Secretary David Blunkett banned all marches in Peterborough for three months as it was feared violence would be caused by the Anti @-@ Nazi League and National Front who both sought to hold protests on the same day .
