The bottom of his back, buttocks and thigh were found.
Two men have been arrested on suspicion of murder after a human torso was found.
The torso was found in clear plastic by somebody in Salford, Greater Manchester, on April 4.
The victim had only been dead for a few days and the bottom of his back, buttocks and thigh were found.
A 42-year-old man was arrested on a bus around midday today, and a 68-year-old man was later arrested.
It is believed the pair are known to one another.
A 20-year-old man who was previously arrested on suspicion of murder was later released on bail pending further inquiries.
Detective Superintendent Lewis Hughes said: ‘Today’s arrests are undoubtedly a significant step in our investigation, and our focus now is questioning the men in custody, which could be key to finding answers.
‘We are continuing to work round the clock looking through every single line of enquiry that we have established, and you may see further searches in the city over the coming days as we work to leave no stone unturned.
‘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.’
Anyone with information is urged to contact 101 or Crimestoppers.
