Archaeologists have discovered up to 40 decapitated skeletons while excavating a former Roman town along the new HS2 train line.
The corpses were among 425 burials in a large 2,000-year-old cemetery in Fleet Marston, near Aylesbury, Buckinghamshire.
Around 10 per cent of the burials were decapitated - with the head placed between the legs or next to the feet.
