A teenager has admitted head butting and then kicking a 53-year-old in the head after he fell to the ground, causing injuries including a fractured skull and brain haemorrhage.
Eighteen-year-old Mathew Shane Kelliher pleaded guilty to a charge of wounding with intent to cause grievous bodily harm.
The police summary of facts said early in the evening on January 26 Kelliher was with a group of associates under the Moorhouse Avenue and Colombo Street overbridge.
Kelliher took exception to comments made by the victim, and they got into a verbal dispute.
Kelliher head butted the man in the face, and pushed him to the ground. He then kicked him in the head before running away.
The victim received a cut to the bridge of his nose, a broken rib, a broken collarbone, a fractured skull, and underwent surgery for a brain haemorrhage. He was in hospital for a week.
Kelliher told police the victim had abused his female friend, and he thought the man had a gun down the front of his pants and was going to shoot them.
In the Christchurch District Court, Kelliher also pleaded guilty to a charge of theft by a person in a special relationship.
Judge Jane Farish read Kelliher the first of the three strike warnings for repeat violent offenders, and remanded him in custody for sentence on May 31. She asked for a pre-sentence report and a victim impact report be prepared for the sentencing. She also referred him for a restorative justice meeting with the victim.
