The body was found in a stream just after 11am. The five arrested are two 28-year-old men, a 30-year-old man, a 35-year-old woman and a 17-year-old woman. They are being questioned at a police station in Belfast. DCI Lee McNevison from Serious Crime Branch said, “We believe we know who the man is, but we will not be confirming his identity until a formal identification has taken place and a postmortem examination has been held.”
