  • Duke of Cambridge landed air ambulance at HMP Highpoint on Wednesday
  • Prince William waited by his helicopter as paramedics treated a prisoner
  • Future King was guarded by four prison guards and royal protection officer
  • Security staff are thought to travel on each of William's emergency flights

Prince William was guarded by four prison guards and his own protection officer after landing an air ambulance at a prison so paramedics could treat an inmate.

The Duke of Cambridge, a pilot for East Anglian Air Ambulance Service, was seen waiting by his helicopter after landing in the grounds of HMP Highpoint in Suffolk.

William remained outside the jail's main building with his security detail for half an hour as medics treated a prisoner who had a seizure.

It is thought that a royal protection officer travels on all of the second-in-line's emergency flights, despite there being limited room inside the Bond Air Services choppers. 

When the Prince started training for the role last year, there was speculation that his security staff would be taught advanced first aid so they could help treat injured people picked up by the air ambulance. 

A neighbour to the category C men's prison told The Sun's Rob Pattinson: 'The helicopter landed a few yards outside the main gate and four prison staff immediately surrounded it to offer Prince William greater protection.

'Lots of people came out of their houses to see what was going on but the staff kept them well away from him.'

Another woman who witnessed the scene on Wednesday said: 'I couldn't believe it. I know he has to be prepared to fly anywhere, but landing on prison grounds? That has to take some guts. Who knows what could happen if the prisoners found out he was there?'

Kensington Palace declined to comment on security matters. 

Officials at the prison - which once housed Moors murderer Myra Hindley - confirmed that a man in his 20s had a seizure and was taken to hospital.

Prince William has worked for the charity since July, fitting in a four shifts on and four shifts off rota around his royal duties.

On his estimated £40,000-year a salary, the royal pays tax of around £6,000 and national insurance contributions of £3,845 - the first direct heir to the throne to do so. 

The Palace say he donates his post-tax salary – estimated to be in the region of £30,000 per year - to charity, but will not specify which.

In July the Mail on Sunday discovered that terrorists could use a mobile phone app to track the movement of the Prince as he flies the air ambulance helicopters.

Experts warned of the ‘extraordinary risk’ to the future King presented by the £2.99 flightradar24 app, which gives away precise details of his helicopter’s position, direction of travel, speed and altitude.

Former police officers said the information presented ‘intelligence gold’ for terrorists wishing to track the Prince’s flightpath in an attempt to shoot him down. 

The helicopter's data was later removed from the app and can no longer be monitored.
