(TheBlaze/AP) -- Denver police are reviewing video footage from city surveillance cameras after a shot was fired through the window of President Barack Obama's campaign office.
Police spokeswoman Raquel Lopez says people were inside the office when the shooting happened Friday afternoon, but that no one was injured. However, a large panel of glass was left shattered.
Lopez added that cameras are in the area of the campaign office on West Ninth Avenue near Acoma Street near Denver's downtown, and investigators are poring over the tapes for any leads.
She did not release any other information, citing an "active, ongoing investigation," but said she isn't aware of any previous threats against this particular campaign office.
The Secret Service referred questions about the shooting to Denver police, and an Obama campaign spokeswoman declined to comment.
This is not the first time an Obama campaign office has been damaged. Mediaite notes that the president's campaign office in Los Angeles was vandalized and shot at with a BB-gun last year, and that in August of this year Occupy Oakland protesters smashed its windows and shouted "leave marijuana alone!"
