**Chicago on High Alert Ahead of NCAA Big Ten Men’s Basketball Tournament Amid Heightened Security Concerns**
CHICAGO (WLS) — As the city prepares to host the NCAA Big Ten Men’s Basketball Tournament starting Tuesday, law enforcement agencies are ramping up security measures to ensure the safety of tens of thousands of attendees at the United Center.
A detailed threat assessment conducted by the FBI Chicago Field Office and reviewed by ABC News has placed authorities on high alert amid ongoing U.S. military tensions with Iran. While no credible, specific threats have been identified so far, both local and federal agencies remain vigilant for any individuals seeking to cause harm.
**Focus Areas for Law Enforcement**
One key concern is the potential for attacks inspired by foreign terrorist organizations. Authorities are currently investigating an incident from this past weekend in Manhattan, where two men were arrested for throwing improvised explosive devices near the mayor’s residence. Federal records indicate a possible connection to ISIS.
Derek Mayer, ABC7’s law enforcement expert and former deputy special agent in charge of the Chicago Secret Service Field Office, emphasized the heightened alert status since the conflict with Iran began.
“The leaders of a country were killed,” Mayer said. “So, law enforcement on American soil needs to be prepared.”
With ongoing offensives in the Middle East, both federal and local law enforcement are maintaining an elevated threat posture at home. This includes increased patrols, additional resources, and extra officers deployed at major events — measures expected to be in effect during the NCAA tournament.
**Unpredictable Threat Environment**
The FBI’s security assessment highlights the complex and unpredictable nature of current threats. It points to risks from so-called “lone wolf” actors motivated by political or social grievances, such as the Highland Park July 4th shooter who killed six and injured dozens.
There is also concern over vehicle attacks targeting soft targets, referencing the New Orleans New Year’s Day attack in 2025.
Another emerging threat detailed in the report is the possible use of drone technology to carry out attacks. Mayer explained: “A small drone can carry a small payload that can wreak havoc. That is something that law enforcement has to be prepared for. And as we know, technology is evolving every day.”
While the report confirms there is no credible intelligence of drone use against the NCAA Big Ten Tournament, it notes propaganda from foreign terrorist organizations like ISIS encouraging drone attacks on sporting events.
**Cybersecurity and Public Vigilance**
Experts describe the threat environment as highly dynamic, pointing to recent cyber-attacks claimed by pro-Iranian hacking groups targeting the U.S., Israel, and NATO allies.
Mayer urged event attendees to remain alert and report anything suspicious. “The general public is law enforcement’s greatest friend,” he said. “If you see something, say something, especially at times like this, when America is in a conflict.”
As Chicago gets ready for one of the region’s biggest sporting events, it’s clear that vigilance and collaboration between law enforcement and the public will be key to maintaining safety.
