Gun Advocates Spook Fast Food Workers Into Hiding in Freezer Jack in the Box employees thought they were being robbed, police said.

May 6, 2014  -- Fast food employees who thought they were being robbed by a group of gun-toting men locked themselves in a freezer to hide, police said.

It turned out the men, some of them from the group Open Carry Texas, were just staging a demonstration of their right to bear arms, Fort Worth, Texas, Police Sgt. Raymond Bush told ABCNews.com.

“When police showed up, there were four to six men carrying rifles,” he said. “The employees were in fear for their lives.”

No arrests were made and the gun owners went home after their demonstration.

The incident happened at a Jack in the Box in Fort Worth on May 1.

Employees spotted the men outside the restaurant. Once police arrived and reassured the workers they were in no danger, at least one employee posed with the group for a photo.

The demonstration was staged by Open Carry Tarrant County, the local chapter of Open Carry Texas, OCT's CJ Grisham told ABCNews.com.

Grisham denied reports employees hid in the freezer, claiming they were the result of a customer's false 911 call.

"There are a lot of people in that area who completely disagree with gun rights," he said. "They have been doing this to us for months now - call the police with false reports of us waving around guns, scaring people."

Fort Worth police said they stand by their report.

Open Carry Texas, which often stages demonstrations, says its mission is to educate Texans about gun safety and encourage citizens to feel safe around gun owners who bear arms in public.
