SALT LAKE CITY -- Prosecutors say a Utah man posed as a federal agent in an attempt to get VIP tickets to a Comic Con event in Salt Lake City.

Jonathon M. Wall was indicted Wednesday on federal charges after the 29-year-old Layton man allegedly claimed he needed passes to catch a fugitive at the event where many attendees wear elaborate costumes.

Authorities say a security official got suspicious of Wall, who was posing as a special agent with the Air Force Office of Special Investigations. The official contacted the Air Force, whose agents confirmed Wall didn't work for them.

Wall faces charges of impersonating a federal officer and making a false statement.

The September comic book convention attracted about 120,000 people and featured "Captain America" actor Chris Evans.

No lawyer or phone number was publicly listed for Wall on Thursday.
