The Orange County Register reports that 58-year-old Yashwant Giri was taken into custody Thursday as he drove away from his Cypress home.
Employees at Placentia-Linda Hospital allege that they witnessed Giri abuse a 16-year-old girl in February 2009 and a 36-year-old woman March 18.
The hospital contacted police in April, the same month Giri resigned from the hospital.
Authorities believe there may be other victims because Giri, an independent physician, works at other hospitals.
