COLUMBUS (AP) — A group of demonstrators stamped the stairs and walls outside the Ohio Statehouse with red handprints and wrote “hands up, don’t shoot” in protest of police brutality, the most recent example of damage to Ohio’s chief symbol of state government since anti-racism protests critical of police began three weeks ago.

State troopers began to wash off some of the red paint on the western side of the statehouse in Columbus on Thursday afternoon as protesters watched on.

“That’s blood on their hands,” Derek Terry, 22, of Grove City, shouted over to troopers, the Columbus Dispatch reported.

Terry, one of the handful of demonstrators, told the Dispatch the paint symbolized how minorities have been the victims of police brutality.

The Ohio Highway Patrol has opened a case to document the damage and try to identify the multiple suspects involved, patrol spokesman Lt. Craig Cvetan said Friday.

Early the morning of May 29, as protests erupted nationally over the death of George Floyd at the hands of Minneapolis police, protesters in Columbus smashed 28 windows at the Statehouse along with storefronts throughout the downtown of Ohio’s capital city
