A police officer told a court he saw pools of blood next to an unconscious man who was allegedly murdered.
Tomas Gulbinavicius, 33, and Janis Karajevs, 30, are on trial at the High Court in Aberdeen accused of killing housemate Aleksejus Zarskus at a property in King Street.
The men, who deny the charge against them, are accused of repeatedly punching and kicking him and stamping on his head on January 15.
Pc Richard Lewis, who was called to the scene that night, gave evidence on the fourth day of the trial.
He was informed a man was injured and two men had already been detained when he was asked to head towards the flat in the city centre.
He described seeing Mr Zarskus in the living room.
“My colleague was performing CPR on him,” he said.
“There were pools of blood either side of his head, he had clear injuries to his face and blood around his nose and mouth.”
The trial, before Lord Uist, continues.
