The Prince of Wales said he was “shocked and saddened” by the “tragic” death of his former nanny’s stepson in a New Year’s Day vehicle attack in New Orleans.

The Metropolitan Police confirmed they were supporting the family of Edward Pettifer, 31, of Chelsea, who was killed in the attack in Bourbon Street, Louisiana.

Authorities have confirmed 14 people died and at least 35 others were injured when the suspect, identified as Shamsud-Din Jabbar, allegedly ploughed a pick-up truck through crowds of New Year revellers.

In a personally signed message posted on the Kensington Palace social media account, William said: “Catherine and I have been shocked and saddened by the tragic death of Ed Pettifer.

“Our thoughts and prayers remain with the Pettifer family and all those innocent people who have been tragically impacted by this horrific attack. W.”

The King is said to be deeply saddened by the death of the stepson of Prince William and Prince Harry’s former nanny in a New Year’s Day vehicle attack in New Orleans. The Metropolitan Police confirmed they were supporting the family of Edward Pettifer, 31, of Chelsea, who was killed in the attack in Bourbon Street, Louisiana.

It is understood the King was made aware of Mr Pettifer’s death through official channels, was deeply saddened, and had been in touch with the family to share personal condolences.

The Telegraph reported that Mr Pettifer was the stepson of Prince William and Prince Harry’s former nanny Tiggy Legge-Bourke, also known as Alexandra Pettifer.

Mr Pettifer was the eldest son of Charles Pettifer, a former Coldstream Guards officer, and Camilla Wyatt, the daughter of a racehorse breeder, according to the newspaper. His half brother, Tom, who is a godson to William, was a page boy at the wedding of the Prince and Princess of Wales in 2011.

The Prince of Wales is understood to have been made aware of Mr Pettifer’s death. Jabbar, a 42-year-old Texan, allegedly got out of the vehicle and fired a gun before being shot by police.

Mr Pettifer’s family said in a statement: “The entire family are devastated at the tragic news of Ed‘s death in New Orleans. He was a wonderful son, brother, grandson, nephew, and a friend to so many. “We will all miss him terribly. Our thoughts are with the other families who have lost their family members due to this terrible attack.

“We request that we can grieve the loss of Ed as a family in private. Thank you.” The New Orleans coroner gave Mr Pettifer’s preliminary cause of death as “blunt force injuries”.

The Met Police said family liaison officers are supporting Mr Pettifer’s family and helping them through the process of returning his body to the UK. The Foreign Office also said it was supporting the victim’s family and was in contact with US authorities.

“Our hearts and prayers continue to go out to the victim’s families,” she said. The attack took place in the city’s popular French Quarter at around 3.15am local time on New Year’s Day.

The New Orleans coroner said one of those killed remains unidentified with the others coming from the US – the youngest aged 18 and the oldest 63.
