'Cowardly attack' fractures man's skull
A man was left with a fractured skull and brain injuries after a "cowardly" assault.
Detective Sergeant Mark Reid said the attack occurred on the driveway of a Linwood property about 2am on Sunday.
Reid said two men and a woman had left a taxi at the Cashel St address when they were approached by a group of four men and two women.
There was an "exchange" between the groups, and one of the men from the larger group followed the trio onto the Cashel St property, Reid said.
The two men were then attacked by the man who followed them onto the property, he said.
"The offender punched one man twice in the face, knocking him to the ground.
"The second man stepped in to protect the first victim and was punched two or three times in the face. He fell backwards while unconscious, with the back of his head striking concrete.
"As a result, he has suffered a fractured skull and brain bleed and was admitted to intensive care at Christchurch Hospital."
Reid described the attack as "vicious and unprovoked".
The offender is believed to have left the scene on foot with his associates.
"This was a cowardly attack that has left a young man with serious injuries.
"We really need the public's help to identify this offender, so that he can be held to account for his actions."
The offender is described as Maori, aged in his early 20s, of medium to stocky build, and approximately 1.7 metres tall.
He was wearing a black hoodie and black cap.
