A man could lose the sight in one eye after being slashed from the temple to the jaw in a random attack.
The 22-year-old was enjoying a night out in Auckland with friends when they were attacked by four men just before midnight on Friday. He left a trail of blood from Myers Park to Aotea Square as he tried to flee with a friend.
Another man, a 21-year-old who suffered a serious stab wound to his chest, was an associate of four men who were charged on Saturday with wounding with intent to cause grievous bodily harm.
Witness Antonio Broughton saw one of the men with facial injuries as he was walking back to his car in Greys Ave.
"He was walking towards me yelling and screaming and I kind of didn't pay any attention because I thought he was just drunk. But it was only when I got closer and saw his whole front was covered in blood. I thought the T-shirt had writing on it but then I realised it was blood."
