James Brooks was jailed for six months by Wellington District Court judge Tom Broadmore.

One of the men involved in a bizarre vampire-style attack on a teenager in Wellington has gone to jail after not completing the sentence he was given in 2010.

James Brooks, 22, looking sombre in a shirt and black jacket and lacking his trademark mohawk, was jailed for six months by Wellington District Court judge Tom Broadmore.

Brooks and two others had been with the teenager on Wellington's Mt Victoria in February 2010 when they restrained him and he was bitten by two of them. He was later admitted to hospital for infected bites on his chest.

Brooks later pleaded guilty to wounding with reckless disregard and was sentenced to three months community detention, 150 hours community work and to pay the victim $400.

He failed to do the community work.

He was given another chance in July last year when Judge Mike Behrens, QC, imposed 18 months intensive supervision instead, designed to help his rehabilitation from drugs and alcohol.

Brooks told the judge then to send him to prison.

However when he came to court today he had not complied with the terms of that sentence either.

Judge Broadmore told him, ''What I am saying Mr Brooks, is it's up to you to change your ways and if not you are going to have a sorry life.''

Brooks told him Care New Zealand did not consider he had a drug or alcohol dependency anymore.

''I was so incredibly happy about that,'' he said.

Judge Broadmore also jailed him for an incident from October last year where he drunkenly yelled and advanced on members of the public in Manners Mall before police arrived.

At the police station he then kicked a police officer in the stomach. He pleaded guilty to assault and disorderly behaviour.
