GWINNETT COUNTY, Ga. -- Police in Gwinnett County believe they've caught a man behind a string of luxury car thefts.

Investigators believe Deshun Williams masterminded a key-swapping theft ring where the criminals take fake key fobs to a dealership, then secretly switch them out for real ones.

Officers say Williams stole a $250,000worth of high-end vehicles, scratched out the VIN numbers, and resold them.

Police are also investigating Williams in connection with another string of stolen cars.

Williams is facing several charges, including theft by taking and theft by deception.

BUFORD, Ga -- Police should always be so lucky. A Buford man was arrested for shoplifting after he called 911 himself.

Alfonso Aguilar, 42, of Buford was spotted by loss prevention officers at the Walmart on Buford Drive Monday night. They followed him out of the store after watching him steal several items.

When the employees identified themselves as loss prevention Aguilar pulled out a knife and
"
swung it widely
"
and ran, according to a Gwinnett County Police incident report.
"
So he actually produces a knife in the course of this trying to resist these two guys who he claims later are trying to abduct him or assault him," Cpl. Jake Smith said.
