MILPITAS (KPIX 5) — A video posted on YouTube shows dozens of stunt-riding motorcyclists popping wheelies at high-speeds on a Bay Area freeway and shrugging off attempts by a California Highway Patrol motorcycle officer to pull them over.

The video posted titled “Cop Chases Bikers Then Biker Makes Cop Leave,” was posted Wednesday on YouTube. Investigators said the video shows a group as many as 50 riders pulling stunts at high-speeds on Interstate 680 in Milpitas earlier this month as they approached a CHP motorcycle officer trying to pull over the lead bike, who is pulling a wheelie.

When the officer was unable to pull over the lead bike, another rider passes the officer while pulling a wheelie. The officer then pulled ahead of the group, only to be met by a third rider who yells to the officer, “you’re not wanted.”

“The behavior displayed by the riders on the motorcycles was extremely reckless,” Ross Lee of the CHP told KPIX 5.

The CHP explains, the officer was trying to pull one guy over, and then another. But each time, fellow bikers would move in.

“The officer had been behind these bikes, and trying to make a stop. The riders, as he would get behind one, would move back into a pack and so he was unable to get one of the riders he was attempting to pull over to the shoulder,” Lee said.

After the officer exchanges a few muffled words with the rider he motions with his hand to “cut it out,” and pulls away from the group.

As the officer speeds out of the frame, other riders can be seen pumping their fists in celebration.

“He made a determination and a judgment call based on his own safety as well as the safety of the general public on the road at the time,” Lee said.

No arrests have been made. The CHP said they will be reviewing the video for clues on who exactly was responsible.

The poster of the YouTube video has not responded to KPIX 5’s request for comment Wednesday night.
