WASHINGTON -- A swastika was found painted on the window of President Barack Obama's campaign office in a Denver, Colo., suburb late Thursday.

The black Nazi symbol was found by building owners painted outside a window of the office, located in the Denver suburb of Conifer, 9News.com reported. The office opened recently in the Jefferson County hamlet.

The Jefferson County sheriff's office did not immediately return a request for comment. 9News.com reports that Obama's campaign has not commented on the incident, which comes a week after a shot was fired into a window of Obama's Denver campaign office.

In 2009 during a Tea Party rally held to oppose the stimulus package on the day Obama signed the bill, a participant waved a sign bearing a swastika in the "O" of Obama's name. The sign holder had a picture taken with conservative activist Michelle Malkin and was reportedly on stage when then-state Senate Minority Leader Josh Penry (R-Grand Junction) spoke.

The swastika incident occurs two weeks after an Obama supporter in Tulsa, Okla., who had an Obama sign on his lawn reported receiving a death threat from a neighbor. Kyle Counts, a 27-year-old law student, told HuffPost that the neighbor engaged him an argument after seeing the sign and then yelled the threat, which was captured on video.

UPDATE: 7:55 p.m. -- Scott Lorditch, a volunteer at the Conifer office, told The Huffington Post that when he arrived at the office on Friday, staffers told him the vandalism occurred overnight. Lorditch said that Obama lawn signs in front of the office were also shredded. He said that while he did not see the damaged signs, when he arrived the signs were no longer in front of the office.
