ABC7 News has shown you how it works: someone rings your doorbell or knocks on your front door and if you don't answer, a team of burglars attempts to break into your home.
Video of this kind of burglary was taken in San Jose and there have been dozens reported on the peninsula.
Now we're getting word that homeowners in Fremont, San Leandro, and Hercules have fallen victim to this kind of scheme as well.
In San Leandro, two victims who were home at the time were held captive by the burglars as they ransacked the house.
