The California Highway Patrol said Hector Martinez, 24, Mike John David Gutierrez, 38, Giovanni Mendez, 19, and Rudy Cadena, 24, were arrested Thursday in connection with the January incident on the 10 Freeway in West Covina, the Los Angeles Times reported Wednesday.
Police said 200 to 250 motorcyclists blocked traffic on the highway before Martinez "performed a burn out for several seconds" and "then proposed to his passenger."
"Several of the motorcyclists on scene applauded, videotaped and photographed the incident, which was posted on YouTube," the police report said.
"After a thorough investigation, four of the main individuals involved in this incident were identified," the highway patrol said.
All four men were charged with misdemeanor public nuisance and unlawful assembly. Martinez was also charged with exhibition of speed.
