Jara allegedly assaulted two patients and police believe he may have fled the country to his native Peru.
Bond for Dr. Jara was set at $3 million.
Jara was working at Stroger Hospital as a resident doctor of internal medicine. In March, he was accused of sexually assaulting a patient during a gynecological exam. That same month, he allegedly exposed himself to a second patient and allegedly assaulted her.
The hospital dismissed him then, and an investigation was launched.
Jara's temporary license to practice at Stroger has been suspended.
