SALT LAKE CITY?Federal agents are seeking six Utah residents with Middle Eastern backgrounds as part of a nationwide effort to question 5,000 foreigners for clues into the Sept. 11 terrorist attacks.

Utah U.S. Attorney Paul Warner declined to release specifics about the six men, The Salt Lake Tribune reported Wednesday.

Warner said the interviews will be strictly voluntary and will not escalate into a witch hunt.

“There will be no coercion, no arrests?it’s just, what can you tell us? Do you know anything?” Warner said.

He said the men might have some information that does not seem important to them, but might be useful to investigators.
