The motorcycle rider nabbed for allegedly filming himself and other bikers doing wheelies while defying a California Highway Patrol motor officer in Milpitas is now facing marijuana charges and was apparently sponsored by the GoPro camera company, authorities said Friday.

Guruardas Singh Khalsa, 32, was arrested at his Brentwood home on Wednesday night with the help of his own posts about the crime on social media, which included video shot by his helmet-mounted GoPro camera, authorities said.

“Mr. Khalsa’s social media and Internet profile describe him as a stunt motorcycle rider,” CHP Officer Ross Lee said. “Postings attributed to him indicated that the GoPro camera company has provided sponsorship to him in relation to his stunt-riding activities.”

A GoPro spokesman was not immediately available for comment Friday.

A search of Khalsa’s home Thursday yielded a loaded rifle and a marijuana grow consisting of about 90 plants, said Lee.

Besides the original accusations of being an accessory to a felony and obstructing a peace officer, Khalsa now faces allegations of marijuana cultivation and the presence of a loaded firearm involved with marijuana cultivation, Lee said.

A video posted last week on YouTube, titled “Cop Chases Bikers Then Biker Makes Cop Leave,” shows dozens of bikers riding south on Interstate 680 near Montague Expressway in Milpitas on Oct. 11. The video, shot by a mounted camera, shows the rider and others popping wheelies at high speed and then converging on a CHP motor officer who tried to pull over one of the bikers.

At one point, Khalsa allegedly pulls close to the officer and makes a hand motion at him. Outnumbered by the group of bikers weaving along the freeway, the officer gives up and eventually pulls over to await for backup.
