A coordinated campaign office shared by Vice President Kamala Harris’s campaign and the Democratic Party in Tempe, Ariz., was damaged by gunfire just after midnight on Monday, the police said Tuesday in a statement to ABC News.
"No one was inside the office during the overnight hours, but this raises concerns about the safety of those who work in that building, as well as those nearby," Tempe Police spokesperson Sgt. Ryan Cook said.
Police said they received calls from those who worked in the office on Monday afternoon and arrived to what they said appeared to be gunshots through the front windows.
Tempe Police said they are analyzing evidence and were taking "additional measures" after the shooting "to ensure the safety of staff and others in the area." A motive for the shooting has not yet been determined and the investigation continues, according to the police.
The same office was shot at just a week prior, on Sept. 16, in an incident the police said appeared to involve a BB or pellet gun. That shooting also happened just after midnight and caused "criminal damage," according to the police.
Harris is scheduled to visit the state on Friday.
In response to the second incident, the Harris campaign offered its thanks to Tempe police.
"Overnight, several shots were fired into our Tempe Democratic Party coordinated campaign office. We are grateful to Tempe Police for coming quickly to the scene and are fortunate no one was present or injured," read a statement from a campaign spokesperson
