Robbery risk as 1.5m leave spare key under the doormat

Home security blunders are rife in the UK, according to a new study that found 1.5 million people leave a spare key under the doormat.

The findings coincide with the UK release of The Bling Ring this week, starring Brit beauty Emma Watson (pictured) and based on the true story of a group of teenagers who break into the homes of Hollywood's rich and famous, pocketing millions of dollars worth of loot.
