A pair of workers at the Lakeshore Plaza Arby’s were pistol-whipped by thieves in ski masks after they arrived at work Sunday morning and opened a rear door for what they thought was a bread delivery.

“One victim was a 17-year-old kid,” police Inspector Brian Danker said. “When he saw his colleague being pistol-whipped, he tried to fight with the suspects, and his heroics caused thetwo suspects to speed up their robbery and get the heck out of there.”

Danker said the thieves are believed to have been involved in other robberies in The City. “They haven’t hit that area before,” he said.

More than $1,000 was stolen during the 8:05 a.m. robbery, according to Danker, which took place near the corner of Sunset and Sloat boulevards.

“They took everything,” said the restaurant’s owner, who asked not to be named.
