An air ambulance has been called to help a man in his 60s who suffered an injury.
An East Anglian Air Ambulance [EAAA] spokesperson said the Norwich aircraft was called out at 1.38pm.
It arrived at Dersingham Recreation Ground a short while later.
The spokesperson said: "The EAAA team assisted EEAST [East of England Ambulance Service NHS Trust] at the scene in assessing and treating the patient. The man was then taken to hospital by the EEAST team."
Several residents took to social media to say they saw the helicopter "flying very low" in the area.
A staff member at the nearby Tropics Fast Food Takeaway also said the helicopter had landed at the play park.
