The number of bank robberies across Oklahoma has nearly tripled in 2013 compared to the year before.
There were 23 bank robberies statewide in 2012. In 2013, the FBI reports that there have been more than 60.
FBI spokesman Rick Rains says investigators are not sure what has caused the increase. But he noted that 2012 was a low year in total number of bank robberies.
Rains says arrests have been made in about two-thirds of the bank robberies committed in 2013. He says the remaining cases will likely be solved soon.
The spokesman says there also seems to be a misperception about how much money robbers are actually able to get away with.
