A pizza shop customer armed with a gun shot and killed one robber and injured another in Levittown, Pennsylvania, NBC reported.

According to the TV channel, two armed robbers entered Porfirio's Pizza and Pasta shop when there were employees and a customer. Presumably, the robbers hit the visitor with a gun after which the latter opened fire and killed one of the criminals and injured the second one.

As it was reported, the customer's gun was properly registered. Police were still trying to confirm whether the man had a concealed carry permit.
