Caretaker killed and two teachers injured in knife attack at Poland school

The 15-year-old entered the primary school in Leszczydół-Nowiny, north of Warsaw, at around 09:00 (07:00 GMT) and attacked the caretaker, 37, before being overpowered by a teacher and the school's headteacher who were also injured.

Polish media report that the caretaker had tried to stop the 15-year-old from entering the school.

Polish police said they had also detained a 17-year-old boy in another town after he had indicated an intention to do "something spectacular" at his school.
