The East of England Air Ambulance Service was called to Wisbech Park this afternoon after a man was seriously hurt when he fell from a ladder.
Emergency crews were called to the area shortly after 12.30pm today following the incident, which involved a man in his 60s.
The East of England Ambulance Service said the man initially attended the North Cambridgeshire Hospital, but was transferred to the Queen Elizabeth Hospital in King’s Lynn when his condition deteriorated.
A spokesman said the man had suffered serious leg and abdominal injuries, though they were not believed to be life-threatening.
Police were also called to the area at around 1.20pm to assist with what a spokesman termed as “crowd control” to enable the helicopter to land.
