Full title reads: "London. 'Smash ... but impossible to grab'! New safety device successfully demonstrated in the West End."

London.

A car draws up in a London street. A gentleman in a bowler hat gets out and walks towards a shop window. People are gathered to watch him.

As he walks to the window he draws back his arm and throws a brick at the window. As the window glass breaks a metal shutter falls down over the window and an alarm begins to go off. The man runs back to his car and drives away.

A man stands next to the broken and shuttered window to explain how this new anti theft device works. It operates by gravity. There is a close up of the broken glass.
