The suspect was struggling with the store owner at the time, according to the Fall River Herald News.

“When I went in, there was a piece of wood on the floor, a two-by-four or a table leg,” Hak told the paper. “I picked it up and hit him (the robber) on the back of the knee. That put him on the ground.

“Then I put him in the arm bar,” Hak continued. “I kept him in that position until the police arrived. By then, he had no gun. Somehow, the gun dropped.”
