Police say someone fired a shot at the Obama campaign's Denver headquarters Friday afternoon.

No one was injured, though people were inside the offices when the incident occurred, said Denver police spokeswoman Raquel Lopez. "It looks like it was one shot that was fired into the structure," she said.

There is a vehicle of interest but not further information.

Lopez said police have a description of a "possible vehicle of interest." She said she could not release that information while detectives are reviewing any available video footage of the incident and pursuing leads.
