In April, pro-Trump demonstrators gathered near Civic Center Park in Berkeley, California to hold a “Patriot Day” rally. Clashes between Pro-Trump and anti-Trump “Antifa” protesters broke out. One person, Eric Clanton, a former professor, decided to use a U-shaped bike lock to assault three people. One of the reported attacks was captured on video, which is featured below (Warning: some strong language). An investigation was conducted and Mr. Clanton was arrested earlier this week (via East Bay Times):

Eric Clanton remained in custody in lieu of $200,000 bail at Berkeley Jail on Thursday and is scheduled to be arraigned at 9 a.m. Friday at Oakland’s Wiley W. Manuel Courthouse. He was arrested on three counts of suspicion of assault with a deadly weapon that isn’t a firearm and assault causing great bodily injury.

In a statement Thursday, police acknowledged that video of the incident, captured by onlookers and posted on social media, helped them identify Clanton as the suspect behind “several violent assaults” that happened April 15 during the demonstration at Civic Center Park on Martin Luther King Jr. Way.

Homicide detectives handled the investigation because of the seriousness of the assaults, police said. Investigators served warrants Wednesday at unspecified addresses in San Leandro and Oakland, the latter of which is where authorities took Clanton into custody.

He surrendered without incident, police said.
