Police, fire and ambulance crews have closed a road in a Cambridgeshire village this afternoon.
Emergency services were called today at midday to reports of a hazardous material incident at Gosmoor Lane, Elm.
Fire crews say a chemical has been spilt but it is unknown what at this time.
A spokesman for the East of England Ambulance Service said: “We were called at 12.03pm to concern of the welfare of four people following a ‘harmful substance incident.
“The ambulance service sent two ambulances, two ambulance officers and a hazardous area response team.
“Three patients have been discharged at the scene. The fourth has suffered a back injury after fainting and is likely to be taken to Queen Elizabeth Hospital in King’s Lynn.”
Gosmoor Lane, Wisbech end, is currently closed due to the ‘multi agency incident’.
