The man who once stalked "Star Trek: Voyager" star Jeri Ryan and executive producer Brannon Braga is behind bars once again.

Marlon Pagtakhan -- convicted in 2001 of making threats against Ryan and her then-boyfriend Braga -- is accused now of harassing members of a coed wrestling club as well as a separate female wrestler from Illinois, according to the San Jose Mercury News. Pagtakhan was arrested in Redwood City, Calif., and pleaded not guilty to the charges Tuesday in San Mateo County Superior Court. He is being held in lieu of $800,000 bail.

Pagtakhan is being accused of stalking six members of a wrestling club in Hayward, Calif., that he was once a member of. The stalking began, authorities said, after club members asked him to leave for being "weird."

At the same time, Pagtakhan was reportedly romantically interested in a female wrestler in Illinois, traveling to the state from California to try and meet her, and repeatedly sending text and instant messages to her.

Police finally arrested Saturday after apparently driving to the wrestling club, putting a pair of boxing gloves on the car, and screaming out challenges to fight. If convicted, Pagtakhan could see up to 20 years in state prison thanks to his previous stalking conviction involving Ryan.

The former Seven of Nine rescued Borg now appears in the CBS series "Shark."
