Detective Superintendent Lewis Hughes, of GMP’s Serious Crime Division, said the arrests were “a significant step” in their investigation and they will now question the men in custody which “could be key to finding answers”.
DS Hughes said: “At the centre of our efforts remains our victim. Our investigation is moving at pace and we are determined to identify him and find out how he has met this tragic outcome.
“This victim could be a father, brother, son, or cousin. He is a man over the age of 40, with white skin tone, believed to be European, and most likely had blonde or light brown hair and blue eyes.”
