Becca Villanueva, a spokeswoman for Kroenke Sports & Entertainment, said she would not discuss the specifics of the incident. Kroenke owns the Pepsi Center and the Nuggets. On game days, the company contracts with Argus, a private company, to run security checkpoints at the admission gates, Villanueva said. But she would not say whether the will call ticket window had Argus security or Pepsi Center employees working there before tipoff.
