A Florida great-grandmother is taking a bite out of crime.
Police in Daytona Beach report Patricia Robertson bit a purse snatcher hard enough to draw blood.
The 73-year-old woman then was dragged several feet while hanging on to her attackers' truck.
Robertson told police a couple snatched her purse at a gas station.
She adds she doesn't know how she got the strength to fight back.
A witness saw the commotion, called 911 and followed the crooks.
Police made the bust and returned Robertson's purse.
She says she almost lost a tooth biting her attacker.
