Social media posts help authorities find Huntington Beach man involved in US Capitol riot

A Huntington Beach man has been arrested and charged with taking part in the attack on the U.S. Capitol. 

Special Agent in the FBI’s Los Angeles field office used social media to identify and locate Mark Simon.

He was allegedly caught on camera breaching the Capitol building and bragging about being inside.

Simon’s posts on social media read "Peacefully Storming the Capital" and "#StopTheSteal."

He was identified by a local police detective who saw video of Simon in the Capitol.

According to the Department of Justice, a YouTube video showed numerous individuals pushing their way into the Capitol. It appears Simon was recording at the time they broke through the Capitol doors. In the video he can be heard saying "In the Capitol baby, yeah" and "2021 Donald Trump". 

The FBI sent those social media posts to the Huntington Beach Police Department for help in identifying the individual. The police department was able to confirm the identity was that of Mark Simon, a known activist in Huntington Beach.

Simon was arrested Thursday morning and has been charged with entering restricted buildings or grounds, unlawful activities on Capitol grounds and disorderly conduct.
