A man has died after being attacked in a Glasgow flat on Tuesday.
Alan Ritchie, 61, was pronounced dead at the scene following the attack that took place on Kennishead Avenue.
Emergency services attended after receiving reports of the incident at around 10pm and the 61-year-old was found seriously injured.
He died a short time later.
Police have now launched a murder enquiry and are looking to trace two men they believe may have vital information.
Detective inspector Alan McAlpine said: “Mr Ritchie has suffered a very violent attack which has resulted in his death and it is vital that we trace the person or persons responsible.
“We believe that this was not a random attack and know that two men entered the block of flats prior to police being called.
“It is vital that we trace these men as they may be responsible for the assault on Mr Ritchie.”
Anyone who has any information that could assist the police investigation is asked to contact them via 101.
