A man who allegedly led an assault on an international school in Cambodia, taking dozens of children hostage and shooting dead a two-year-old Canadian boy, may have been motivated by a grudge against a former employer, police said today.

Six masked men took 70 students and three teachers hostage at an international school in north-western Cambodia today.
