Ralston police had little trouble tracking down a bank robbery suspect on Monday afternoon.  

Police say a woman walked into the Wells Fargo branch at 84th and "L" and presented a note to the teller, that claimed she had a bomb, and left with an undisclosed amount of cash.  

Thanks to help from witnesses, police found 23-year-old Shantoria Valentine just a few blocks from the bank in front of the Ralston Middle School.  

Valentine is being arrested for robbery, terroristic threats, and threatening to use explosives; all of which are felonies.
