A senior British army officer has been charged with sexually assaulting a female military officer in Canada. Lt-Col Christopher Davies, 45, was arrested following an alleged incident on 10 April this year, police in Ontario have said.

The officer, who was in Canada on a temporary posting, has been bailed to appear in court on 15 September.

An army spokesman said it was aware of an investigation involving a serving British army officer.

The alleged assault occurred at Fort Frontenac, in Kingston, following commemorations for the World War One Battle of Vimy Ridge, on 9 April, police said.

The alleged victim – a 52-year-old female officer – had attended a military function at the fort.

She then allegedly went to a bar with other guests, including Lt-Col Davies. Police say she reported having being sexually assaulted in her hotel room in the early hours of the following day.

Lt-Col Davies was arrested and charged earlier this week.

He has since been released but was ordered to surrender his passport and has been barred from leaving Ontario ahead of a court appearance.

“We are aware of an investigation being conducted by Kingston Police into an alleged incident that took place in April this year involving a serving British army officer,” a British army spokesman said.

“As the case is sub judice it would be inappropriate to make any comment.”
