Movie theater chain Regal Entertainment Group has begun to check bags in response to shootings at theaters around the country.

Several local TV stations reported online that customers noticed the change in Texas, Virginia, Florida and Ohio beginning earlier this month, reports Fox News. 

On its website, the company says "security issues have become a daily part of our lives in America" and says that bags and backpacks are subject to inspection before entering.

National Amusements Inc.'s Showcase chain, which runs about 30 theaters in the northeastern U.S., says on its website that it has banned backpacks and packages and reserves the right to search purses and bags. It says the policy, which began Aug. 7, will be in place "for the time being."
