(CNN) A 30-year-old California woman was abducted from a male acquaintance's residence in the Bay Area and is being held for ransom, police said Tuesday.

The male acquaintance, also 30, witnessed the kidnapping of Denise Louise Huskins from the Vallejo home, and he is not a suspect in the case, said Vallejo Police Lt. Kenny Park.

"Ms. Huskins' whereabouts are unknown, and we are treating this matter as a kidnap for ransom," Park told reporters. "We're worried about Ms. Huskins' welfare. We don't know where she's at. And that's why we're coming to the public asking for their help."

Huskins, who has been living in Vallejo the past year, is from Huntington Beach in Southern California, police said. She works as a physical therapist, police added. She is employed at a Kaiser Hospital, CNN affiliate KGO reported, citing her Facebook page.

A cousin of Huskins, Amy Mattison, told CNN affiliate KPIX that the 30-year-old man is Huskins' boyfriend and she was abducted from his residence.
