U.S. Sen. Susan Collins’ Biddeford office was apparently the target of vandals again. 

Collins’ office released photos of the sidewalk at the office’s entrance, where someone used red spray paint to write “Blood on her hands.”

The vandalism appears to have occurred overnight on the eve of Election Day.

This is the second time someone has used red spray paint to graffiti the outside of her office. A similar incident occurred in late September. 

“This is another incident in a series and the second attempt at our Biddeford office to intimidate the Senator and her staff,” Collins’ Chief of Staff Katie Brown said. “These tactics are disturbing, but not effective. Our staff is undeterred and on the job.”

Biddeford is where a resident and Colombian national – Johan Sebastien Guerrero – was shot and killed by a federal immigration agent in July, sparking protests and a march to Collins’ office.
