An air ambulance landed in Cassiobury Park earlier this week to assist with a patient transfer between hospitals.
Photos snapped on Monday around 2.50pm shows the helicopter flying low over the park and landing by some goal posts, with a land ambulance also at the scene.
The East of England ambulance service says the air ambulance was called to assist with a patient transfer between hospitals rather than responding to a specific incident.
It is unclear whether the air ambulance had been dropping a patient off at the park or if it was picking up a patient.
No further information has been issued.
