Emergency services are attending a medical emergency at a house in Saxmundham.
Police, forensics and the ambulance service have been seen at an address on Chapel Road in the town.
A police spokesman said a cordon has been put in place so an investigation can take place but said there was no threat to the wider community.
Barry Wyatt, who was visiting a friend in the area, reported seeing police and forensics officers as well as an ambulance on the scene.
A neighbour said the property is believed to be owned by a couple.
She added she had been shocked by the presence of the emergency services, saying nothing like that had happened in the 16 years she had lived in the area.
