(JTA) — A woman was arrested for her alleged involvement in a spree of anti-Semitic and racist graffiti in Norman, Oklahoma.

Allison Johnson, 45, also is suspected of painting swastikas and other hate messages in Oklahoma City.

Democratic Party headquarters in both Oklahoma City and Norman both were vandalized.

Johnson was arrested on Thursday on a charge terrorist threats. She turned herself in, according to the Norman police, NBC reported.

Three locations in Norman, located about 20 miles from Oklahoma City, were vandalized with swastikas, ethnic slurs, and other racist graffiti on Tuesday night, according to local reports. The Firehouse Art Center, McKinley Elementary, and the Cleveland County Democratic Party Headquarters were all defaced, the Norman Transcript reported.

The epithets include “Gas the Jews,” the word “Jewess” painted in red on a statue that had swastikas painted over its eyes, and “hang n***er kids,” all decorated with swastikas.  The graffiti also made violent threats against prominent Jewish Americans such as academic Barbara Spectre and political commentator Bill Kristol.

At the end of March, graffiti was scrawled in Oklahoma City on a building that is also home to state agencies, non-profit groups and businesses. The phrases included “Welcome to Germany,” “Trump hates Israel,” ”Gas the Jews,” and “The Goyim know,” as well as the number sequence 1488, which is a reference to Adolf Hitler.
