Pro-Palestinian Arab graffiti spray-painted on the exterior of a Michigan law firm is being investigated as a hate crime, police in suburban Detroit said, according to The Associated Press.

University of Michigan regent and attorney Jordan Acker called the vandalism “antisemitic” and said staff at the Goodman Acker law firm's Southfield headquarters discovered it Monday morning.

Splotches of red paint were left on the “Goodman Acker” sign above the building's doors. “FREE PALESTINE” was spray-painted in black upon the building’s walls, while “DIVEST NOW” and “U-M KILLS” — a reference to the University of Michigan — were spray-painted in red upon at least one window and a sidewalk.

Southfield Police Chief Elvin Barren said investigators believe the graffiti was left between 1:39 and 1:46 a.m. Monday. The FBI and other agencies are assisting in the investigation.

“Make no mistake that targeting individual Jewish elected officials is antisemitism,” Acker, who is Jewish, told reporters.

“This has nothing to do with Palestine or the war in Gaza or anything else,” Acker continued. “This is done as a message to scare Jews. I was not targeted here today because I am a regent. I am a target of this because I am Jewish.”

Acker was elected to the university board in 2018 and is one of eight regents.

Police last month broke up a pro-Palestinian Arab encampment at the University of Michigan, citing a threat to public safety.

Late last week, a pro-Palestinian Arab encampment at Wayne State University in Detroit was broken up, with at least 12 people arrested.

Similar pro-Palestinian Arab encampments have been set up at campuses across the US in recent weeks.
