Detectives have arrested a Milwaukie man suspected of vandalism during a demonstration police determined to be a riot last week in Portland.

Gavin Hotchkiss, 20, is facing riot and first-degree criminal mischief charges, according to court records. He's suspected of being involved in vandalizing a Jeep driven through downtown Portland during an anti-Donald Trump demonstration on Nov. 10, Portland police said in a news release.

The Jeep's driver was heading south on Broadway near Pioneer Courthouse Square, American flags streaming in the wind, when people -- apparently protesters -- ran after the vehicle and ripped away the flags.

The Oregonian/OregonLive saw part of the sequence unfold. Police didn't publicize Hotchkiss' alleged role in the vandalism.

Note: The video contains explicit language, and the Jeep's driver said he and the Jeep's occupants weren't trying to incite protesters.

Hotchkiss was jailed Thursday in Portland and released on his own recognizance, according to Multnomah County jail records.

Hotchkiss was convicted of assault in the fourth degree in 2014. In 2015, he was convicted of robbery in the third degree and theft in the first degree for stealing a bicycle, according to documents filed in Multnomah County Circuit Court. All three convictions were felonies.

He is also currently charged with assault in the third degree and charges related to identity theft, court records show.

Police Chief Mike Marshman estimated the riot resulted in more than $1 million in damage.
