http://www.businessweek.com/ap/financialnews/D9MK4EJ00.htm Denver police said Thursday they believe employees who witnessed an alleged sexual assault at the airport responded appropriately by calling for help, countering earlier statements by the woman's family that some people may have walked by without helping. Police spokesman Sonny Jackson said Denver International Airport employees called security to report Tuesday's incident in a near-empty concourse. Airport security then contacted police, who with airport officers were at the scene within three minutes, Jackson said. He would not say how many workers responded and declined to release additional details, saying the case was under investigation. Jenny Schiavone, a DIA spokeswoman, said an initial airport review found that employees followed proper procedure in responding to the incident. She did not release details of that review and said an informal review of whether all procedures were followed is under way.
