NumBytes 44: Flash Robs

Social networking is all the rage, including 'flash mobs' that arrive at a preset time and place to perform silly dances for You Tube videos. But criminal gangs are using flash mob tactics to loot stores. According to a July 2011 National Retail Federation survey of 106 US retail companies, 79% reported being a victim of an organized robbery with multiple thieves in the past 12 months, with 50% being targeted two to five times -- usually smash and grab style heists. These robberies are usually performed by groups or gangs of juveniles who already know each other. Of troubling note, 10% reported these gangs using flash mob tactics where they do not know each other -- criminals learn about a retail hit via text or e-mail and just show up.

The survey found juvenile offenders were involved in 83% of the events and social media or texting was known to be the communication vehicle in 42% of the apprehended cases. The affected retailer or responding police department made apprehensions in 50% of the incidents. In one example, on June 23, 2011 in Philadelphia, a gang of 40 criminals stormed a Sears store stealing thousands of dollars in sneakers, socks, watches, and other items. Police apprehended 15 juveniles and one adult, who were arrested for retail theft and conspiracy.

The NRF suggests increased vigilance on the part of associates to report unusual gatherings in front of the store, whether it is in a mall, plaza, or street shopping district.
