Ambulance crews alerted officers at around 10.17am last night after the 63-yeaar-old male was attacked Mossgiel Crescent.
Tayside Police attend and found a male in a house there.
He had suffered serious injuries and despite their efforts, the man was pronounced dead at the scene.
The area was quickly searched however the attacker was not identified.
The victim’s name will not be released until he has been formally identified and next of kin have been informed.
Senior Investigating Officer, Detective Inspector Gary Ogilvie today confirmed that a man had been seen leaving the address at around the time of the incident. He has still to be identified and traced.
DI Ogilvie said: “A man wearing a dark hooded top, with the hood up was seen leaving the area. We want to know who that man is and would appeal for him to come forward or for anyone who knows him to get in touch with the police.
“If you were in the area, did you see a man acting suspiciously? If so, please get in touch. The information you have could prove to be invaluable to our investigation.”
