PLACED IN CUFFS
Former NFL star Eddie Lacy is fortunate he didn't hurt himself or anyone else on the night of his DUI arrest last month ... 'cause cops claim he was driving around with a blood alcohol content level over FOUR TIMES the legal limit.
The Scottsdale Police Dept. says it all happened back on Sept. 30 ... after a woman dialed 911 and told dispatch that someone matching Lacy's Audi SUV description was driving so erratically, she was worried they were "going to kill somebody."
