According to the police, a 30-year-old man was approached in the pub by two men at around 12.55am. One of them hit him in the face with a bottle before both left the scene, leaving the man with a serious facial injury.
The first suspect, the one who struck the man with the bottle, was described by police as male, white, 30 to 35-years-of-age, 6ft, wearing a beanie hat, a padded gilet and light coloured trousers, possibly tracksuit trousers.
The second suspect was described as male, white, in his early 50s, between 5ft 4in and 5ft 5in, of slim build, short receding hair and wearing a light top and jeans.
Detective Constable Liz McIntosh, Cambuslang CID, said: “We have still to establish exactly why this assault took place, but it would appear that the man in his 50s had been in the bar prior to the assault taking place, left for a short time, returning with suspect who attacked the injured man.
“They both made off from the pub after the attack and the injured man was taken to the Glasgow Royal Infirmary where he was treated and has since been released.
“The pub was busy that night and we have established that there were a number of people within the Wee Mill at the time of the attack who may have attempted to assist the injured man. I am appealing for any witnesses who were present at the time of the assault to contact police as it is vital that we trace the persons responsible for this violent attack.
