Police have arrested two men on suspicion of murder after a woman's body was found in the boot of a car.
The body was found by police in a green Ford Escort which had been driven to Ipswich police station on Saturday.
Two men from Ipswich, aged 28 and 35, were arrested shortly after 2230 GMT on Saturday and were being held in police custody.
Officers have cordoned off an area around the Suffolk Ski Centre in Wherstead as part of the investigation.
Potential crime scene
The police spokesman said the woman's identity would not be revealed until she had been formally identified and her family informed.
A post-mortem examination was due to be held on Sunday at Ipswich Hospital.
The spokesman said: "We've got two people in custody and will not be releasing anything else apart from the name of the deceased, possibly the cause of death and what is going to happen to the people currently in custody."
The spokesman said an area around the Suffolk Ski Centre was being treated as a potential crime scene.

Paul Trinder, the owner and manager of the ski centre, said he did not know anything about what had happened but that police were keeping him informed.
"Sunday is one of our busiest days of the week," he said.
"We have six instructors on and all those lessons have had to be cancelled.
"We are waiting to hear what the CID are planning to do. I think they are planning a fingertip search. We are doing whatever the inspector tells us."
Mr Trinder said the cordon extended around the ski centre, fields and the road running alongside the centre.
"This has nothing to do with the ski centre. It's the access road to the ski centre," he added.
