Meanwhile in Maryland . . .

An elderly man was making a bank withdrawal from his account — it was a BIG withdrawal — and the bank teller ROBBED him!

This is like bank robbery inception.

Nathan Newell (19) is . . . errr was . . . a bank teller at a Freedom Federal Credit Union branch when the 78 year old customer came in to make his withdrawal.

Later that night, Nathan went to the guy’s house . . . totally forcing his way in . . . attacked the man and robbed him!

When the guy’s stepdaughter (57) pulled a gun on Nathan, that’s when he ran.

Authorities were able to piece things together and arrested Nathan at the bank a couple days later.
