The Palestinian allegedly took a bite of the Israel Prison Service psychiatrist while he was being held in the Russian Compound detention center in Jerusalem, lightly wounding the doctor.
The psychiatrist was taken to the Hadassah Ein Kerem Hospital in Jerusalem where he was quickly taken into surgery after a piece of his nose was dislodged.
Legal and disciplinary action will be taken against the Palestinian detainee, and he could be charged with assault.
The detainee will be held in detention until the completion of proceedings after he was arrested for illegally entering Israel and misleading a police officer.
After being brought into the holding facility Sunday afternoon, the detainee was visited by the psychiatrist who was supposed to take the Palestinian in for a medical examination.
As the jailers opened the cell door, for reasons yet unknown the Palestinian jumped on the awaiting psychiatrist and bit him on his nose. The Palestinian was quickly apprehended by the officers and returned to his cell.
An MDA paramedic team was alerted to the detention facility and they administered first aid on the bitten shrink, later evacuating him to the Jerusalem hospital.
