Ex-NFL RB Michael Bennett Arrested -- Allegedly Screwed GF's Parents In $325k Scam

Ex-NFL running back Michael Bennett -- a 1st round draft pick in 2001-- was arrested in California Thursday after cops say he forged his GF's parents names to take out $325k in loans.

According to police, the victims -- both over the age of 65 -- became suspicious when they got mail from brokers about the loan.

Officials say Bennett -- who spent 10 seasons in the NFL -- stole important financial documents from his girlfriend's parents and forged loan docs to get the money.

And what did he spend the cash on??

"It looks like he used the money to purchase at least one vehicle and go on some shopping trips," Sgt. Ed Crosby told SFgate.com.

Cops say Bennett has already confessed to the crime -- he's currently behind bars ... being held on $1 MILLION bail. He's been charged with 9 felonies including grand theft, burglary, forgery and elderly abuse.
