Brittney Alexander, 22, has been booked into Houston jail on an aggravated robbery charge.
According to authorities, Alexander ordered a teller at the Chase bank on 1102 Silber Road to give her money.
"This is a robbery. I have a gun and give me all the money and nobody will get hurt!" a note read.
At a second location, Alexander got away with $900 after threatening the bank teller.
Police believe she is connected to other robberies across the area.
Last week, two females struck three Chase banks with a demand note. The duo got away with an undisclosed amount from two locations.
