The air ambulance was called to a medical incident in an east Suffolk town.
Emergency services were spotted in Leiston at about 9pm on Sunday.
The air ambulance was seen landing at St Margaret's Football Club in Abbey Road in the town at the weekend.
However, the patient's condition is not known at this time.
A spokesman for the East of England Ambulance Service said: "We were called just before 9pm to a private property in Leiston and sent an ambulance, ambulance officer vehicle and the East Anglian Air Ambulance.
"Due to patient confidentiality, we are unable to give out more details.”
