Man, 71, fends off young robber with ice scraper
Mar 17 02:20 PM US/Eastern
RAPID CITY, S.D. (AP) - Police said a 71-year-old man, armed only with an ice scraper, frustrated a 20-year-old would-be robber who approached him with a knife. Police said the man was scraping ice off his car Friday when the 20-year-old pulled out a knife and demanded money.
Police Sgt. Pete Ragnone said the man used his ice scraper to fend off the attacker—who then ran to his girlfriend's home nearby.
That's when a fight broke out between the 20-year-old and his girlfriend.
The would-be attacker surrendered to police and faces charges of attempted first-degree robbery and aggravated assault-domestic violence.
