A US pizza worker was shocked when a workmate overpowered a disguised robber - and it turned out to be her father.

Stephanie Martinez was getting money out of a cash drawer when Rudy Sandoval fought back against the intruder, knocking off his wig and sunglasses.

Ms Martinez was so surprised when she saw the robber's face that she dropped the money, reports the Dallas Morning News.

"I said, 'Don't hit him again! That's my dad!' And he said, 'What's he doing here?' and I said, 'I don't know!'"

Police say the suspect, Benjamin Ramirez, 41, ran out of the pizzaria in Denton, near Dallas, Texas, to a pick-up truck, where Ms Martinez's mother and husband were waiting.

But officers don't think Ms Martinez knew her family was planning the robbery.

"We will not be filing charges against her," Sgt. James Brett said. "Her husband told us she didn't know. He knew they were going to rob someplace, but he thought it was going to be a convenience store."

Witnesses followed the pickup and helped lead police to it, where Ramirez, Sonia Palacios, 38, and Jose Miguel Martinez, 26, were arrested.

All three have been charged with aggravated robbery.
