TULSA, OK -- Police are working another bank robbery Friday, the third robbery of a financial institution since Thursday morning. 

Friday's robbery was at the Red Crown Credit Union at 2700 East 51st Street. 

Police say a man handed a teller a note, then told her not to read it and just give him money or he would shoot, but he didn't show a gun.  

A Tulsa Police dog tracked a scent from the bank, but lost it a couple of blocks away.  Police believe the suspect may have gotten into a car. 

The suspect is in his 20's, about 5 feet-six inches and weighed between 150 to 170 pounds.

The suspect was wearing a brown stocking cap, oversized Carhart jacket, black gloves and white square-shaped reading glasses.
