Bankrobber Leaves Tip: Firefighter Jesus Ventura, Alleged Thief, Left $20 For Teller

He might be a bank robber, but hey, the guy's a gentleman.

A firefighter was arrested on Tuesday after allegedly robbing a Dallas Chase Bank -- and then leaving a $20 tip for the teller.

Cops said Jesus Ventura, 37, of Irving entered the bank branch in broad daylight and told the teller, "Give me all the money" several times," NBC-DFW reported.

After he was given an undisclosed amount of money Ventura reportedly slid a $20 bill under the glass and told the teller, "Here's a tip for you."

Dallas cops collared Ventura after he allegedly robbed a nearby gas station after the first hesit, according to the Associated Press.

In his first court appearance Wednesday, Ventura told the court that he has bipolar disorder, anxiety and depression and wasn't on medication Tuesday. Cops said he was incoherent when they arrested him.

The fireman was put on paid leave in March when he reportedly walked into a Dallas fire station, fired a semi-automatic pistol and then pointed the handgun at other firefighters.
