Dr Anthony Bell, the medical director of St John of God Hospital in Midland, is charged with one count of aggravated assault occasioning bodily harm over an alleged violent incident in April.
Siddique rose to prominence when she successfully sued the British Army for discrimination after it failed to acknowledge her role in rescuing two SAS soldiers from war-torn Iraq.
In court documents, Bell called the assault allegations “baseless”, claiming Siddique had “shown a desire to ruin his life” since their separation.
The veteran emergency physician also claimed his employer wouldn’t allow him to keep treating patients if the case went public, putting extra strain on WA’s struggling health system.
St John of God Hospital has since confirmed Bell has taken a leave of absence until the matter is finalized.
