State police said drivers clamored to pick up cash on an interstate in Indianapolis after the back doors of a Brinks armored truck swung open, causing hundreds of thousands of dollars to fly out.

Sgt John Perrine, state police spokesman, said investigators don’t know exactly how much cash was in the truck when its lost its load around 9am Wednesday on Interstate 70 on the city’s southwest side.

Troopers at the scene initially said up to $600,000 had flown across the interstate, but police later said the exact amount was not known.

But Perrine said it was definitely hundreds of thousands.
