The robber was so trapped that not even shooting at the door could save him. It got to a point he had to kneel down and beg people outside to help him out, sensing the danger of being apprehended by the police.

Though the incident happened in April last year, police released the video just last week, following the conviction of Bell to five years in prison.

Karina Leon told KHOU-TV, "It was in broad daylight, I was cashing out a customer and she had a baby. I think I was handing her cash, then this guy walks in with a hoodie on."

Leo added that "As soon as he went into the office I just immediately got out and got the customer out."

But how was Leo able to get the robber trapped? She explained, "I just locked him outside because whenever you lock the door outside, from the inside you can't open it so I knew he wasn't going to be able to open it."

The police were so full of admiration for the brave lady that officer Jeff Brieden of the Houston Police Robbery Division admitted, "Everything that [Leon] did just worked in our favor, she locked the door, he wasn't able to get out."
