Police are asking nicely, for now: If you scooped up any of the money that fell out of an armored truck in Baltimore, please return it.

In what must be the best tunnel commute ever, thousands of dollars flew out of a Brink's armored truck Wednesday night in the Baltimore Harbor Tunnel.

Police say the truck's door security malfunctioned.

And, as people will do, drivers stopped in both lanes and began picking the money up. That caused a jamup in the tunnel that lasted eight hours.

Police aren't sure how much money spilled. But, they say, some drivers on the scene did cooperate with police.

Maryland Transportation Authority Police say anyone who took some of the cash and hasn't given it back can return it without being prosecuted for theft.

They've set a deadline of 5 p.m. Saturday to turn the money in.
