San Antonio police arrested a man they say robbed a Domino?s Pizza at gunpoint this summer.

The second arrest is the second this week in connection with the July robbery at the eatery on Goliad Road.

According to an arrest affidavit, 31-year-old Nicholas Anthony Arzola confessed to robbing the pizza place, saying he committed the crime after a heated argument with his girlfriend over money.

The affidavit stated Arzola's girlfriend, later identified as Amanda Stout, held the door open for Arzola while he robbed the restaurant.

Stout was arrested earlier this week and charged with robbery, the affidavit stated.

According to the affidavit, Arzola admitted to using a handgun to force employees to give him money from the cash register, all while wearing two blue bandanas to cover his face.

Police released still images from surveillance video of the robbery last month.

According to the affidavit, the images led to several Crime Stoppers tips from people who recognized Arzola and Stout.

The surveillance video also showed Arzola jumping over the counter to steal cash from the register, and showed Arzola and Stout running toward a getaway vehicle.

Arzola was charged with aggravated robbery.
