Police warn about 'sliders' who rob you while you're at the gas pump

Watch this surveillance video of a woman filling up her SUV. See how the silver car pulls up next to her like just another customer.

Now watch, while the woman focuses on the gas pump the crook crouches down, opens the passenger door and grabs her purse.

The entire crime took nineteen seconds. You've just seen a "slider" at work.

Here's another example. While a woman is inside the store this car pulls up, a man checks the doors and takes a quick peek inside.

The woman comes out and while she's pumping gas the man jumps through the driver's side window, grabs her purse and is gone. She never noticed a thing.

Houston police officer Jim Woods says these crooks hit all parts of town--watching for women who leave their purses on the passenger seat, doors unlocked and are distracted.

"A vehicle is not a secure location for your property.  They say it's sliding because they're sliding below the eye level of the door", says Woods.

Woods says these burglaries can be stopped by women keeping their purses out of sight or taking their purse with them when they pump gas and always locking their doors.

Like Sydney Zenon who goes a step further, "I don't hold the pump, I usually click the holder on the pump so I can have time to actually scan what's going on around me."

Andrea Kahle says she does lock her doors, but leaves her purse out in the open.

"It should probably be in the glove compartment, underneath the seat somewhere. On my side versus the passenger side, lesson learned," Kahle said.
