Prince William and Kate Middleton Convoy Crash: Elderly Woman in 'Serious Condition' After Collision With Royals' Police Escort

An 83-year-old pedestrian was seriously hurt in a collision with a police motorbike escorting Prince William and Catherine, Duchess of Cambridge, from London to Windsor on Monday.

The woman, named by Kensington Palace as Irene, was taken to hospital after the crash, where she remained in a serious and stable condition as of 10.30 a.m. local time Wednesday, Newsweek confirmed.

A spokesperson from police watchdog, the Independent Office for Police Conduct⁠, said an investigation into the incident had begun, but it was too early to speculate as to the specific circumstances surrounding the crash.

The collision occurred at 12.50 p.m. local time on Upper Richmond Road in Richmond, southwest London, according to an earlier IOPC statement. IOPC investigators will speak to local residents and view CCTV from the scene to determine how the incident took place, the spokesperson said.

The investigation was launched "in line with procedure," the IOPC stated. The independent body is responsible for scrutinizing situations involving police in which individuals are seriously hurt or killed.

"Our immediate thoughts are with the injured woman and her family and those affected by the incident. The woman's family has asked that its privacy be respected at this time," the IOPC's statement read.

The Cambridges promised to "stay in touch" with Irene and her family during every stage of her recovery," a spokesperson from Kensington Palace told the BBC. The duke and duchess are believed to have sent flowers and well-wishes to the elderly woman.

When they travel, senior members of the royal family are often accompanied by security convoys supplied by London's Metropolitan Police.

The incident occurred during the couple's journey to Monday's Garter Day ceremony at St George's Castle in Windsor. William and Kate attended the event, which saw King Felipe VI of Spain installed as a Supernumerary, or 'Stranger', Knight of the Garter.

Netherlands' King Willem-Alexander was also installed in the Order Monday, as the Dutch royal family's official Twitter profile noted.

The Order of the Garter is one of the most prestigious orders of chivalry in the British honors system. The only orders of higher status are the Victoria Cross and the George Cross.

Queen Elizabeth II recently gave Kate official regalia after making her a Dame Grand Cross of the Royal Victorian Order, a dynastic order of knighthood set up by Queen Victoria.

Appointments to the Royal Victorian Order, which are made personally by the Queen, recognize services to the monarch.
