Shocking CCTV emerged of a man being glassed in the head from behind while having a meal in a restaurant.
The 23-year-old victim was rushed to hospital where he was left with 14 stitches on his head.
The incident took place at a restaurant in Sydney’s Chinatown area in Haymarket at around 9.15pm on February 27.
New South Wales Police has renewed its public appeal and released the security camera footage in a bid to look for two men who may be able to assist with the investigation.
Footage shows the victim in a grey t-shirt emblazoned with a Mickey Mouse, chatting with a friend while a man in black top approaches him from behind.
The man suddenly strikes the victim to the back of his head with a Corona beer bottle and slowly returns to his table.
The victim covers his head while some confused onlookers walk over to help him stop the bleeding.
At some point, the man returns and slaps the victim in the face.
He then leaves the restaurant with his friend.
The injured diner was subsequently taken to St Vincent’s Hospital for treatment.
Sydney City Police Area Command Crime Manager, detective Inspector David El-Badawi told 2GB on Wednesday morning: “It’s a dog act, to put it bluntly.
“There were no words exchanged, there were no interactions at all prior to this incident taking place – it was totally unprovoked and random.
“We need the community’s assistance to help us put the final pieces together and put those responsible before the courts.”
They are looking forward to speak with two men who were at the restaurant when the assault took place.
The first man has been described as being of Asian appearance, about 175cm-180cm tall, of medium build, aged in his 30s, with black short hair.
The man is seen in the video wearing a black shirt and black trousers.
The second man has been described as being of Mediterranean appearance, about 180cm-185cm tall, of medium build, aged in his 30s, with black short hair.
