A man was assaulted as he left a pub in Leigh.
The 47-year-old left the Ale House pub on Henrietta Street at around 11pm on Saturday 11 January 2014 before he was attacked.
He was taken to hospital and suffered internal eye injuries.
Police Constable Susan Martland based at Wigan East INPT said: “Unfortunately the victim does not remember anything about the actual assault and woke up in the ambulance. The last thing he remembered was saying goodbye to his friends before going to the toilet. From the information we have received, we believe the attack took place somewhere outside.
“Although from the surface it looks like he has suffered a black eye, his orbital socket and floor is fractured and also has restricted movement.
“I would ask anyone who may have witnessed any kind of assault at around 11pm to contact us. We do not have any description of the offenders but the victim is 5ft 9in tall, his head is clean shaven and has dark prominent eyebrows. On the night he was assaulted, he wore a cream polo t-shirt, black jacket and black jeans.”
Anyone with information should phone police on 0161 856 7225 or the independent charity Crimestoppers, anonymously, on 0800 555 111.
