Security is being stepped up on the LIRR, local sports arenas, hotels and other attractions as counterterrorism officials are reviewing new potential threats against the country.

Counterterrorism officials issued security bulletins Tuesday to police around the nation about terrorists' desire to attack stadiums, entertainment complexes and hotels. They follow another bulletin warning transit systems to increase security measures.

The warnings are in light of a terror probe involving suspects in Queens and Colorado. Former New York Homeland Security Advisor Michael Balboni says federal officials are working with officials on the local level to make sure potential targets are secure.

The MTA says there's no credible threat to the city's subway system and commuter trains, but it is not taking any chances.
