() A woman was arrested in connection to a string of vandalism incidents at a Colorado Tesla dealership, believed to be directed against Tesla founder Elon Musk, according to court documents.

Lucy Grace Nelson, 40, was arrested Monday in Loveland after returning to the dealership with “additional incendiary devices” and materials used for vandalism, police said.

Nelson faces several charges, including possession of incendiary device or explosives during a felony, criminal mischief and criminal attempt to commit a class 3 felony.

Police are working with the Bureau of Alcohol, Tobacco, Firearms and Explosives and federal charges were likely.

Nelson posted bond and was released from jail Tuesday. Her next court appearance is scheduled for March 7. Police are still investigating her alleged motive.

The arrest affidavit suggests a second person is involved, citing surveillance video from one of the six incidents since Jan. 29, which seems to have a smaller build than Nelson. However, it identified Nelson as the person seen at other times.

Additionally, footage captured someone spray painting an obscenity believed to be aimed at Musk, while other footage captured Molotov cocktails being thrown into a row of Tesla vehicles, causing damage to four cars worth $220,000.

Police found spray paint, gasoline and other materials in Nelson’s car when she was arrested.

The incidents are under investigation, and the case is part of growing concerns over Musk’s influence and recent protests at Tesla storerooms across the U.S.
