About 2.10am today, police were made aware of a man who had been found deceased in another house on the same property.
At this stage, his death was being treated as unexplained.
Wilson said scene examinations would continue to take place throughout the day to help determine what occurred, and police were not ruling out any further arrests or charges.
Two post-mortems would also take place in due course.
Wilson said police would like to speak with anyone who has information about what happened, or who may have visited the Old Coach Rd address between 7pm on December 31 and 3am today.
Anyone who can help is asked to make a report through 105, either online or over the phone, and reference file number: 260101/9901.
