Shot fired into Obama campaign office in Denver

Denver: A gunshot was fired into President Barack Obama's downtown Denver re-election headquarters on Friday while campaign workers were inside but no one was struck, police said.

Denver Police Detective Raquel Lopez said a worker inside the office called police in mid-afternoon to report that a bullet had shattered a window pane.

"Right now, no one is in custody and investigators are looking at surveillance video to see if a vehicle can be identified," Lopez said.

Lopez said it was a single shot and no one inside was physically injured.

Detectives are not aware of any threats made to the campaign, but are exploring all possibilities, she said.
