A movie theater chain in the Northeast has banned moviegoers from bringing in backpacks and packages in the wake of attacks at theaters that were about half a month apart in Louisiana and Tennessee.

"To ensure the safety of our guests and employees, for the time being, we are prohibiting any and all backpacks and packages as well as reserving the right to inspect the contents of any purse or bag prior to admission," Showcase Cinemas, owned by National Amusements, Inc., said on its website.

Rachel Lulay, a spokeswoman for National Amusements, said the policy was implemented two days after an ax-wielding, pepper-spraying man attacked an audience at a screening of "Mad Max: Fury Road" at a Nashville theater.

The two most recent attacks follow other high profile incidents of violence in movie theaters, like a confrontation over texting turned fatal in Florida and the Colorado movie theater massacre that left 12 dead more than three years ago. 

As Security reported, a study conducted last week by research firm C4 found that less than one-third of moviegoers would favor metal detectors and pat-downs at the entrance of movie theaters.
