The New Orleans Police Department is teaming up with the Orleans Parish and Jefferson Parish sheriff's offices as well as the Louisiana State Police to beef up patrols in the coming days.

During Thursday's news conference, law enforcement agencies reminded the public to follow the rules or face the consequences.
'Very important for us to remember to impress upon the visitors that are here, we want them to certainly have a good time and enjoy themselves and not make it my way,' said Orleans Parish Sheriff Marlin Gusman.
Increased patrols is just one of a string of security measures being put into place as Tiger and Tide fans arrive to town. The Superdome is currently in 'security lockdown mode.' 'Dome officials say visitors entering and leaving the facility are required to pass through metal detectors.
