A demonstrator, who was in favour of recalling California Governor Gavin Newsom on Tuesday, was severely injured after being attacked by an assaulter, according to US media reports. 

Law enforcement authorities of California's San Rafael area have requested assistance from the civilians of the state to locate the assaulter, according to reports from Patch citing the city's police department.

The assault, which happened at the United States 101 freeway's Coleman pedestrian crossing, left one person with a broken jaw. The individual was taken to a local hospital.

Tief Gibbs, who was a part of the rally, said, "He was slashing our signs. And he slashed one sign completely down. It's completely torn and destroyed", according to reports from ABC News.

Gibbs added, "The assailant came towards him (a demonstrator) and pushed him back and started punching him."

The assaulter reportedly fled the scene after severely injuring the demonstrator.

Polls in California recall election will close at 8 p.m. PT — or 11 p.m. ET — tonight. "We already know what a lot of those (early votes) are. We know they’ll be heavily Democratic. A lot of those people are Democrats who voted early," explained CNN’s National Political Reporter Maeve Reston. 

Larry Elder, a member of the Republican party and the top candidate in the fray against Governor Gavin Newsom, has said he believes "there might very well be shenanigans, as there were in the 2020 election." 

Former United States President Donald Trump also jumped on the bandwagon by issuing a statement saying, "Does anybody really believe the California Recall Election isn't rigged?", according to reports from Associated Press.
