Girls, keep your “It” bags close to your body as you get out of your car. Bag snatchers more and more are finding that is the perfect moment to strike, more than when you’re eating in the resto or strolling absent-mindedly in the mall.

As one woman was getting out of her car in front of a restaurant in San Juan, seven guys pounced on her, grabbed her bag, then sped off in a van.

And you know how heavy women’s bags are these days; they weigh a pound or two, so that it’s hard to keep them hooked on your arm.

The woman, in this incident, lost today’s “It” bag—a Givenchy Antigona.

So now we know why you sometimes spot a heavy Birkin being carried by a matron’s barong-clad bodyguard.
