BALTIMORE (AP)- Police around the region are stepping up their presence outside movie theaters following a shooting at a Denver-area theater that left at least 12 people dead.
Baltimore police spokesman Anthony Guglielmi says moviegoers this weekend will notice extra police patrols.
He says there's no specific threat that has been made in the city, but that police want to ward against any potential copycat shootings.
The shooting occurred early Friday in Aurora, Colo., when a gunman walked into a theater, released a canister of gas and opened fire during opening night of the Batman movie "The Dark Knight Rises."
In Montgomery County, police spokeswoman Angela Cruz says the department has stepped up its presence at movie theaters and is asking officers to be vigilant and alert.
