An armed man, claiming to be law enforcement, has been detained at Charlie Kirk’s memorial site in Arizona. 

The man was detained on Friday at State Farm Stadium in Glendale, which is set to host Kirk’s memorial service on Sunday September 21. 

Kirk, aged 31, tragically lost his life on September 10 during his ‘American Comeback’ tour, being shot in front of a crowd of students and supporters at Utah Valley University.

Anthony Guglielmi, a spokesperson for the Secret Service, informed Fox News Digital that the US Secret Service, in collaboration with local law enforcement in Glendale, Arizona, is investigating an individual displaying suspicious behavior at State Farm Stadium.

The man, who is yet to be identified, was approached by Secret Service and said he was a member of law enforcement and armed.

According to a source familiar with the situation, reported by the New York Times, the person was found carrying at least one gun and a knife and showed ‘inactive law enforcement credentials.’

‘The individual is not a member of authorized law enforcement working the event and is currently in custody,’ Guglielmi added.

Secret Service and local law enforcement are investigating the incident and determining why he was at the location.

The service, called Building a Legacy: Remembering Charlie Kirk, is set to begin at 11am local time. 

‘This event is first come, first served based on stadium capacity,’ according to the event’s website. 

‘Indoor overflow will be available next door at the Desert Diamond Arena. Please be informed that enhanced security measures may lead to longer waiting times than usual.’

As of Friday, the lineup of speakers included Kirk’s widow, Erika Kirk, along with Trump and Vance, White House Chief of Staff Susie Wiles, Secretary of State Marco Rubio, Department of Health and Human Services Secretary Robert F. Kennedy Jr., Secretary of War Pete Hegseth, Director of National Intelligence Tulsi Gabbard, Donald Trump Jr., Tucker Carlson, White House advisor Stephen Miller, and Sergio Gor.
