Seattle police are hunting for a man in a wheelchair accused of sexually assaulting a 31-year-old patient at a local hospital.

The woman, who wasn't identified, was attacked about 7 a.m. Saturday morning in her room at Swedish Hospital, Seattle police told FOXNews.com.

Surveillance video captured the culprit's face, and authorities hope someone will recognize him and come forward.

"Our detectives are confident that this is the person we're looking for, based on the investigation," Seattle Police spokesman Officer Mark Jamieson told FOXNews.com. "We don't have a name on this suspect. We're hoping somebody knows this person and will contact us."

Jamieson wouldn't release other details about the victim, saying only that she was a patient when she was attacked but declining to disclose whether she has been released.

He also wouldn't talk about specifics of the investigation or why police believe the man in the photos is the attacker. Swedish Hospital contends he wasn't a patient there, but police said he was receiving treatment when the crime occurred.

The surveillance footage is not from inside the hospital, and the assault wasn't caught on camera, according to Jamieson.

Police believe the suspect may actually be able to walk. He is described as a Hispanic male in his 40s last seen in a motorized wheelchair wearing a sweater with horizontal red, blue and green stripes

Authorities are asking anyone with any information to call 911, 1-800-222-TIPS or (206) 684-5575.
