Alan King and his 63-year old girlfriend, Judy Tompson are walking across St Mark's Square in Venice in the sunshine.

It's the last day of their holiday in Italy.

Two young women approach them. One carries a baby and comes up to Judy, making a fuss about something. The other woman shoves a newspaper in Alan's face.

In the moment of surprise, the woman grabs Alan's bumbag and unzips the front pocket.
