To counter a growing threat for retailers, the National Retail Federation (NRF) has released a white paper providing guidelines and protocols for dealing with “flash robs.”

The NRF reports that 79 percent of more than 100 retailer companies it surveyed have been victim to a multiple offender crime in the past year. Of those, 10 percent involved flash mob tactics where people suddenly assembled in one location.

A growing number of flash robs involve violence. This past weekend, a Germantown, Maryland, 7-Eleven was a target of several dozen youths storming the store at 2:00 am, fleeing with hundreds of dollars of merchandise.

 “The number of people involved in this [shows they] clearly had a plan…They were in control of that store from the minute they were in there taking items off the shelves,” said Montgomery County Police Capt. Paul Starks.
