A doctor has pleaded not guilty to a series of historic sexual assault charges which are alleged to have taken place at various hospitals.

Dr Michael Salmon, 78, has denied rape and four counts of indecent assault involving four victims under the age of 16 between 1972 and 1985.

Some of the offences are alleged to have taken place at various hospitals in Buckinghamshire, including Stoke Mandeville where Jimmy Savile once had an office and is believed to have committed a series of sex offences for years.

He was arrested in November 2013 under Operation Yewtree, the Met Police investigation into sex offence allegations set up in the wake of the Savile scandal.

Salmon, a former consultant at Stoke Mandeville, pleaded not guilty when he appeared at Reading Crown Court. A trial date has been set for January 2015.

Salmon was released on bail and will appear next in court in November for a preliminary hearing.
