Homeland Security Investigations “Most Wanted”:

US Immigration and Customs Enforcement, Homeland Security Investigations (HSI), is seeking assistance in locating HSI fugitives for prosecution. HSI is vigorously pursuing efforts to apprehend, or assist other law enforcement agencies in apprehending fugitives who are deemed threats to national security. For more information see the HSI “Most Wanted” website.

Advisory System:

The Department of Homeland Security has created a color-coded advisory system so that protective measures can be applied to reduce the possibility or impact of an attack.

• Imminent Threat Alert (Red Alert)
• Warns of a credible, specific, and impending terrorist threat against the US
• Elevated Threat Alert (Orange Alert)
• Warns of a credible terrorist threat against the US

NTAS Alerts will only be issued when credible information is available.

These alerts will include a clear statement that there is an imminent threat or elevated threat. Using available information, the alerts will provide a concise summary of the potential threat, information about actions being taken to ensure public safety, and recommended steps that individuals, communities, businesses and governments can take to help prevent, mitigate or respond to the threat.

The NTAS Alerts will be based on the nature of the threat: in some cases, alerts will be sent directly to law enforcement or affected areas of the private sector, while in others, alerts will be issued more broadly to the American people through both official and media channels.

NTAS Alerts contain a sunset provision indicating a specific date when the alert expires – there will not be a constant NTAS Alert or blanket warning that there is an overarching threat. If threat information changes for an alert, the Secretary of Homeland Security may announce an updated NTAS Alert. All changes, including the announcement that cancels an NTAS Alert, will be distributed the same way as the original alert.
