A man was airlifted to hospital after a medical emergency was reported at an Ipswich supermarket.
Police, paramedics and the air ambulance were called to Sainsbury's in Hadleigh Road at about 2.50pm on Thursday.
A spokeswoman for the East of England Ambulance Service said paramedics were called to reports of a person in cardiac arrest.
The Essex and Herts air ambulance, two land ambulances and an ambulance officer vehicle were sent to the scene.
A man was later airlifted to the Norfolk and Norwich University Hospital for further treatment, the ambulance service confirmed on Friday morning.
The superstore was closed while emergency services attended the scene, with police sealing off the car park.
It has since reopened.
Confirming the closure on Thursday, a Sainsbury's spokesman had said: "Our Hadleigh Road Superstore was temporarily closed to support the emergency services.
"We will reopen as soon as possible and are sorry for any inconvenience this may cause.”
