Police arrested a 20-year-old man for alleged vandalism and allegedly damaging cars at a Toyota dealership during an anti-Trump protest that police declared a riot, officials said.

Mateen Abdul Shaheed was arrested at an Estacada residence on Tuesday, police spokesman Sgt. Pete Simpson said. He was booked into Multnomah County Jail on six counts of criminal mischief in the first degree, Simpson said.

Police say Shaheed committed multiple acts of vandalism during the anti-Trump protest last Thursday. Police believe that a small group of protesters caused more than $1 million of damage during the protest, which they classified as a riot about three hours after it began.
