A woman was shot during a brazen armed robbery Monday night and it was all caught on surveillance video.

The woman, who is in her twenties, was working behind the cash register at a Little Caesar's restaurant when three armed men came into the El Cerrito, California eatery.

At the start of the robbery, one of the men began pointing his gun at the woman demanding the restaurant's cash.  

Fox Affiliate KTVU reported:

"She was doing everything they told her to do," explained El Cerrito Police Officer Sid Hubbs, as he played the video.

The man with the gun shot the clerk anyway. The bullet struck her in the arm.

The surveillance video has no sound, but at the moment of the shooting, you can see two terrified customers in the background flinch, turn away and hug one another.

As the clerk was bleeding, the two suspects forced her to open the shop's safe, according to police.

In the video, you see one of the men hop the counter and run away. Police said a third man was waiting outside the store, acting as a look-out.

While the cameras don't show the robbers' faces, the weapon used in the crime is clearly visible in the video.

"It looks to be sort of a break-action pistol, like possibly a shortened, 4-10 shotgun," Hubbs said.

The gun caught investigators' eyes, because it's not the type of gun they usually see in armed robberies.

"I don't think I've ever seen one on the street," Hubbs said.

"If somebody has seen that weapon in the possession of somebody they know. It's not a very common weapon, so if someone has seen it, they might be able to help us solve the crime of who's done his," said El Cerrito Police Lt. Robert De La Campa.

The restaurant opened for business the next day and the employee who was shot is recovering at home.
