Twenty-two people in the UK have been thrown from bouncy castles in high winds since 2011, leading to one person being killed, figures have shown.

The research by BBC Inside Out East included the case of seven-year-old Summer Grant, who died when the castle she was on blew away from its moorings and bounced down a hill in Harlow, Essex, in March 2016.

The case led to calls to tighten regulations around the safe use of inflatables.

As part of the research, a BBC team carried out a test showing the impact of strong winds on bouncy castles.
