Detectives are investigating the shooting of two men on a traveller site near one of the UK's biggest military air bases.
Investigators think the killings in Beck Row, Suffolk, last night could be linked to a shooting incident on the same site a few weeks ago.
The site - near the United States Air Force base at Lakenheath - was cordoned off today as scenes-of-crime experts tried to establish what had happened.
Police said one man was found dead on the ground and a second body was discovered in a burning car.
Officers investigated after a vehicle was shot at on February 17. No-one was hurt but a number of people were arrested.
Locals said the site was created about five years ago near another established traveller site.
Police said they were called shortly after 10pm yesterday after a member of the public reported gunfire.
Nearby residents - many of whom work at the air base - were evacuated.
