No pleas were entered and the doctor was granted bail to appear at Aylesbury crown court on 14 October.
A Thames Valley Police spokesman said: “The charges are in connection with incidents which occurred at the Stoke Mandeville Hospital in Aylesbury and Wycombe General Hospital, High Wycombe, between September 2005 and August 2018.”
Buckinghamshire Healthcare NHS Trust confirmed they no longer employ him. A spokesman for Buckinghamshire Healthcare NHS Trust said: “We can confirm that Salman Qureshi is no longer employed by the trust.
