An inquiry into the attacks carried out by Valdo Calocane will hear evidence in London from Monday.

Two men, aged 31 and 48, and a woman, aged 23, were pronounced dead at the scene.

The survey asked pupils as young as 14 about their sexual experiences but parents said they were not told about the nature of the questions.

They have been named locally as Eddie Hill, 20, and Jayden Long, 19, from Norfolk.
