POLICE are slowly tightening the net around a serial rapist and possible psychopath who attempted to stab to death one of his victims in Magalluf in the early hours of last Friday morning - a 21-year-old British woman from County Durham . Closer investigation at the scene of the attack has revealed the kitchen knife which the assailant used in an attempt to kill his victim. With chilling indifference and taking his time, he had allegedly wiped the instrument clean of blood and placed it alongside other kitchen instruments in a flat where the young woman lived. Another woman had been attacked days before but had been too shocked to report the assault.
