A man is facing a handful of charges related to his alleged involvement in a massive roving dirt bike sideshow that closed the eastbound lanes of the Bay Bridge earlier this month.

Jose Mendoza has been charged with two counts of felony evasion and one misdemeanor count of battery on a police officer, according to the Alameda County District Attorney’s Office.

“This conduct created an extremely dangerous situation for law enforcement officers and snarled traffic on the Bay Bridge,” said District Attorney Ursula Jones Dickson.

Mendoza is accused of taking part in a May 3 sideshow that came to an end that Sunday afternoon on the Bay Bridge after winding its way back and forth between Oakland and Berkeley and then over to San Francisco and back to the East Bay.

Oakland Police Chief James Beere said Monday that the group had been under investigation for about two months and that officers, including undercover officers and drone operators, were keeping tabs on participants.

At some point, as the group was on the eastern span of the bridge headed back to Oakland, a large contingent of officers moved in to make traffic stops, arrests and to impound vehicles.

The resulting traffic jam lasted for at least an hour.

Beere said more than 100 officers were involved in the investigation, pursuits, arrests and impoundments.

Police initially said nearly 80 dirt bikes and ATVs were impounded and nine people were arrested. On Thursday, OPD officials said four people were arrested on suspicion of committing felonies and 19 were cited and released on misdemeanor offenses.

So far, the District Attorney’s Office has only announced charges for Mendoza.

Prosecutors say Mendoza, 30, “drove recklessly within the blocked-off section of the bridge at high speed while marked California Highway Patrol vehicles pursued him,” according to a news release.

“Investigators further allege that after Mendoza slowed down and officers attempted to detain him, he resisted arrest by refusing commands, attempting to flee, and attempting to strike an officer during the encounter,” the District Attorney’s Office said.

Additionally, Mendoza was on felony probation at the time and the District Attorney’s Office has filed a petition to revoke his probation.

He is being held on $50,000 bail at Santa Rita Jail and is scheduled for a pretrial hearing in Alameda Count Superior Court on July 2.
