A southeast San Antonio resident identified as 61-year-old James Sabbs is accused of using his parents car and committing a robbery at a Subway restaurant not far from his home.

An arrest warrant affidavit stated that San Antonio police officers responded to a silent alarm that had been set off at Subway in the 400 block of Pecan Valley Road around 2:15 p.m. Monday.

Detectives said the owner told them a man who acted like he had a gun under his shirt walked in and demanded cash, shouting, "This is a robbery."

The owner said he then handed over $80 from the cash register to the man, the affidavit stated.

Although surveillance cameras captured the event, police were unable to download the video, the affidavit stated.

Instead they took pictures of the screen, showing the suspect.

According to the affidavit, Subway employees were also able to write down the license plate number of the suspect's car, the affidavit said.

Detectives, using that information, tracked down the owners who told them their 61-year-old son was using the car at that time, the affidavit stated.

Police said they also showed the couple a copy of the surveillance pictures and they positively identified Sabbs, their son, as the man in them, the affidavit stated.

Sabbs was arrested Tuesday on a charge of robbery.
