Ambulances and the air ambulance attended the scene.
A male has been taken to hospital following 'a medical incident' in Weymouth.
A spokesman for the South Western Ambulance Trust said the air ambulance and two ambulances attended the scene, after recieving a call just before midday today.
The confirmation came after residents reported seeing the air ambulance land on the Marsh playing fields in Weymouth.
The spokesman said they do not believe the incident is connected to emergency services closure of roads in Weymouth around the same time, in which two men were arrested in connection with the supply of drugs.
