THE parents of two students whose bodies were pulled from canals refuted police claims they drowned accidentally. One of the students managed to phone his parents and for over an hour they heard howls and screams, sadly the police did not record the phone call. Is this another one of the “pushers” victims or is something much stranger going on. Tragic David Plunkett’s chilling screams, heard by a 999 call handler, were not taped because the recorder was not working. The officer who dealt with the “distressing” call was so appalled by the blunder she later resigned.
