Updated The Hampshire and Isle of Wight Air Ambulance flew low over houses to land in Riverside Park on Tuesday (Sept 15) at around 10.45am for just over an hour. Read more for further pics/video clips.
Paramedics were seen heading for the Triangle where a road ambulance was parked near the junction of Manor Farm Road and Cobden Avenue - although it's unclear if that was a related incident.
Paramedics from the helicopter reportedly went towards Tescos.
