Police in Ohio said on Friday they had arrested a man after he allegedly ran a U.S. Congressman off a road, threatened the politician and his family, and yelled antisemitic slurs and waved a Palestinian flag before fleeing.

Authorities have identified the man as Feras S. Hamdan of Westlake, Ohio. The Rocky River Police Department said the suspect ran Miller off the road on Interstate 90 and left the area before law enforcement arrived. The 36-year-old suspect voluntarily turned himself in, according to police, and is awaiting a court appearance.

After an interview with police, Miller filed a complaint against Hamdan alleging aggravated menacing and sought a criminal protective order. Local police continue to investigate with assistance from the U.S. Capitol Police, the Ohio State Highway Patrol, the Federal Bureau of Investigation, the U.S. Attorney’s office and the Rocky River prosecutor.
