While officials say there are no credible threats following the bombing in Nashville, Long Island residents say they are still concerned. 

Both Nassau and Suffolk police say they are continuing to receive updates from both the FBI and NYPD on what is now being called an intentional act.

Commissioner of Nassau Police Patrick Ryder said in part, "At this time we do not believe there's any direct nexus here to Long Island; however, we are disseminating an intelligence bulletin to remind members of situational awareness. We continue to intensify patrols around all areas of concern."

Suffolk police shared a similar message saying, "While there is currently no credible threat in Suffolk County, the department is monitoring intelligence and working with our partners in law enforcement to ensure the safety of the residents of Suffolk County."

Security Expert Denis Monette says as authorities on the ground in Nashville continue to sweep for more devices and review surveillance video, agencies around the country will monitor busy areas and critical infrastructure for anything suspicious.
