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

Stephanie Martinez was clearing a till when her co-worker fought back against the intruder, knocking off his wig and sunglasses.

She was so shocked she dropped the money she told 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 car 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," Sergeant 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 car 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.
