An investigation has started into whether authorities could have done more to support a 24-year-old mother, who died after falling from rocks on Dartmoor in Devon.

Katherine Hooper and her eldest son Joshua, five, died in the fall on Friday.

The body of Ms Hooper's two-year-old son Samuel was later found by police officers at her home in Paignton. A serious case review has now been launched.
