Political vandalism has struck Denver, Colorado yet again as GOP nominee Donald Trump’s campaign office was defaced a second time in a 24-hour period, police reported.

In the latest attack, a large rock was thrown through the front window of the same office that suffered a graffiti attack earlier in the day.

Denver Police Department spokesman Tyrone Campbell informed CNN of the second attack saying, “We are investigating a second incident of vandalism in the city at Donald Trump’s office.”

Police note that they have a suspect in custody for the rock throwing incident.

There was an earlier incident on November 4, as well, when vandals painted vile slogans on the outer wall of the building. The office windows were also painted over.

Some of the vandalism included the words “pervert” and “thief” and were painted in large block letters on the brick facade of the building.

“It’s an anti message. We’ll investigate it using all the tools we have at our disposal including viewing electronic devices to determine who did this,” Denver police spokesman Sonny Jackson told the media after the initial attack.

A series of attacks on Republican campaign offices have been seen this year. Not long before the first incident in Denver, the office of the Alamance County, North Carolina, Republican Party was vandalized.

The Alamance County GOP office is not the only one in North Carolina to be attacked this election season. In mid-October the GOP office in Hillsborough, North Carolina, was gutted by a firebomb. After the incident, local Republicans accused the Obama-controlled Bureau of Alcohol, Tobacco, and Firearms (ATF) of attempting to cover up the political motivations behind the attack with its investigation into the incident.

In addition to the attacks noted above, Donald Trump’s new hotel in Washington D.C. suffered vandalism when slogans such as “No Justice No Peace” and “Black Lives Matter” were painted on its walls.

The GOP nominee’s star on the Hollywood Walk of Fame was also attacked by a pick-wielding liberal who destroyed the marker on October 26. The person was later arrested.

Recently, undercover videographer James O’Keefe unveiled a video showing Democrat operatives explaining how they employ political violence to intimidate opponents and to win elections.
