How to avoid being 'cyber-flashed'

Police are investigating a "new" crime of cyber-flashing after a commuter received an indecent image on her phone as she travelled to work.

The victim, Lorraine Crighton-Smith, received two pictures of an unknown man's penis on her phone via Apple's Airdrop sharing function.

It was possible because she had changed her iPhone's settings to allow anybody to "Airdrop" photos to her device.

This video shows how to change your settings to switch Airdrop off when you are not using it.
