Washington (CNN) Police outside Washington have said there is no threat to an office building that is occupied by USA Today and its publisher, Gannett, after the building was evacuated following reports of a man with a weapon.

Fairfax County Police Chief Col. Edwin C. Roessler Jr. said Wednesday afternoon that authorities had received a 911 call that an ex-employee was in the building with a weapon. In a second press conference later on in the day, Roessler later said he was "grateful" to report the incident was a "non-event."

"We do not have any evidence that a crime occurred," he said.

Roessler said the person who police had been looking for was located in a different part of Fairfax County and police were talking with that individual. He said there was no evidence that person had committed a crime.

USA Today, in an update on Twitter, said that reports of a man with a gun were "mistaken."
